System Integration Manual 1 System description 1.1 Overview u-blox C200 wireless modules integrate a complete CDMA 1xRTT 153 kb/s packet data modem into a single module solution. These modems are certified to operate on US CDMA carriers. In addition they can operate on carriers requiring a SIM data card interface. 3G CDMA 2000 1xRTT Characteristics CDMA Terrestrial Radio Access Frequency Division Duplex (FDD) operating mode Dual-band support: Band Class 0 – US Cellular Band Class 1 – US PCS CDMA Packet Switched data up to 153 kb/s DL/UL Table 1: 3G CDMA 2000 1xRTT characteristics These modems are US CDMA certified to support 1xRTT data speeds on US CDMA carriers Sprint and Verizon. FW75-C200 is strictly a data modem for embedded solutions while LISA-C200 also supports audio (analog and digital) functionality. Data communication is through 2 data interfaces; 5 wires UART and Full Speed USB. The interfaces are intended to support a vast quantity of AT commands that will enable easy adoption to existing host application processors. Power on is initiated by HW logic and Power down by HW logic and SW control. LISA-C200 antenna interface is provided through a 50 ohm pad while FW75-C200 uses the popular “U.FL” RF connector. Other key components are the extensive SW AT commands meeting the needs of : Carrier AT commands Industry standard AT command both 3GPP and 3GPP2 u-blox AT Commands CDMA-2X-11004-3 Preliminary System description Page 6 of 43 LISA-C200 & FW75-C200 - System Integration Manual 1.2 Architecture ANT Digital and analog voice (**) Diplexer RF Transceiver UART 3G PA 19.2 MHz 3G PA LNA SAW Filter 32.768 kHz Wireless Base-band Processor USB GPIOs (**) LNA Memory Power On Vcc (Supply) Power Management Unit HW shutdown (*) HW Reset (**) V_INT (I/O) (*): FW75 (**): LISA-C200 Figure 1: Block diagram 1.2.1 Functional blocks LISA-C200 & FW75-C200 modules consist of the following internal functional blocks: RF front-end, RF transceiver, Baseband section and Power Management Unit. RF Front-End The Antenna connector is directly connected to the Diplexer which separates the 800 and 1900 MHZ bands. Each 800 & 1900 MHz RF chain are connected to their respective transceiver paths via duplexers as shown in prior block diagram. Each duplexer provides the filtering and Rx/Tx path separation before connecting to the LNA and RF PA devices. A separate shield compartment houses the 800 MHZ and 1900 MHZ RF power amplifiers. This compartment provides high Tx signal isolation, preventing de-sensing of the Rx frontend circuitry. RF Transceiver The transceiver includes the following key components: Dual-band 800 & 1900 MHz CDMA transceiver, excluding the RF Power Amplifiers, duplexers and diplexer. 19.2 MHz Crystal Oscillator While operating, the RF transceiver performs direct up-conversion and down-conversion of the baseband I/Q signals, with the RF voltage controlled gain amplifier being used to set the uplink TX power. In the downlink path, the internal LNA enhances the RX sensitivity. An internal automatic gain control amplifier optimizes the signal levels before delivering to the analog I/Q to baseband for further digital processing. CDMA-2X-11004-3 Preliminary System description Page 7 of 43 LISA-C200 & FW75-C200 - System Integration Manual In all the modes, Tx & Rx RF synthesizers are an on-chip voltage controlled oscillator are used to generate the local oscillator signal. The frequency reference to RF synthesizers are provided by a free running 19.2 MHz XO. The Rx path locks and tracks to the base station carrier. An learning algorithm is implemented to capture the temperature characteristic of the xtal, comparing the XO and carrier frequencies, while measuring the thermistor in close proximity to the crystal oscillator. A lookup table is saved over temperature and time. The known frequency difference of the free running crystal oscillator is corrected in the baseband processor enabling quick acquisition. Baseband section and power management unit Another shielding section includes all the digital circuitry and the power supplies, basically the following functional blocks: Wireless baseband processor, a mixed signal ASIC which integrates: Microprocessor for controller functions, CDMA upper layer software ARM9 coprocessor and HW accelerator for CDMA Layer 1 control software and routines Dedicated HW for peripherals control, as UART, USB, etc Memory system in a Multi-Chip Package (MCP) integrating two devices: NOR flash non-volatile memory DDR SRAM volatile memory Power Management Unit (PMU), used to derive all the system supply voltages from the module supply VCC 1.3 Pin description Table 2 provides a summary of the module pin names and descriptions.

This is achieved by hardware design utilizing a power efficient circuit topology (Figure 2), and by power management software controlling the module’s power saving mode. 2 x 3G Power Amplifier(s) u-blox C200 Memory NOR Flash RF Transceiver DDR SRAM Linear LDO VCC Linear LDO EBU Switching Step-Down I/O Switching Step-Down CORE Linear LDO Analog Linear LDO SIM Linear LDO RTC 42 µF VCC VCC Power Management Unit Baseband Processor V_INT VSIM 4.7 µF 2.2 µF Figure 2: Power management simplified block diagram Pins with supply function are reported in Table 3. LISA-C200 & FW75-C200 modules must be supplied via the VCC pins. There is only one main power supply input, available on the three1 or five2 VCC pins that must be all connected to the external power supply LISA-C200. CDMA-2X-11004-3 Preliminary System description Page 10 of 43 LISA-C200 & FW75-C200 - System Integration Manual The VCC pins are directly connected to the RF power amplifiers and to the integrated Power Management Unit (PMU) within the module: all supply voltages needed by the module are generated from the VCC supply by integrated voltage regulators. When a 1.8 V or a 3 V SIM card type is connected, LISA-C200 & FW75-C200 modules automatically supply the SIM card via the VSIM pin. Activation and deactivation of the SIM interface with automatic voltage switch from 1.8 to 3 V is implemented, in accordance to the ISO-IEC 7816-3 specifications. The 2.8 voltage domain used internally also available on the V_INT pin, to allow more economical and efficient integration of the LISA-C200 & FW75-C200 modules in the final application. The integrated Power Management Unit also provides the control state machine for system start up and system shut down control. 1.4.2 Module supply (VCC) LISA-C200 & FW75-C200 modules must be supplied through the VCC pins by a DC power supply. Voltages must be stable: during operation, the current drawn from VCC can vary by some orders of magnitude. Name Description Remarks VCC Module power supply input VCC pins are internally connected, but all the available pads or pins must be connected to the external supply in order to minimize the power loss due to series resistance. Clean and stable supply is required: low ripple and low voltage drop must be guaranteed. Voltage provided must always be above the minimum limit of the operating range. GND Ground GND pins are internally connected but a good (low impedance) external ground can improve RF performance: all available pads or pins must be connected to ground. Table 3: Module supply pins Higher ESD protection level can be required if VCC is externally accessible on the application board. Higher protection level can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor array) on the line connected to this pin. The voltage provided to the VCC pins must be within the normal operating range limits as specified in the LISA-C200 Data Sheet [1] or FW75-C200 Data Sheet [2]. Complete functionality of the module is only guaranteed within the specified minimum and maximum VCC voltage operating range. Ensure that the input voltage at the VCC pins never drops below the minimum limit of the operating range when the module is switched on. Operation above the operating range maximum limit is not recommended and extended exposure beyond it may affect device reliability. Stress beyond the VCC absolute maximum ratings can cause permanent damage to the module: if necessary, voltage spikes beyond VCC absolute maximum ratings must be restricted to values within the specified limits by using appropriate protection. When designing the power supply for the application, pay specific attention to power losses and transients. The DC power supply must be able to provide a voltage profile to the VCC pins with the following characteristics: Voltage drop during transmission must be lower than 250 mV FW75-C200. CDMA-2X-11004-3 Preliminary System description Page 11 of 43 LISA-C200 & FW75-C200 - System Integration Manual Any degradation in power supply performance (due to losses, noise or transients) will directly affect the RF performance of the module since the single external DC power source indirectly supplies all the digital and analog interfaces, and also directly supplies the RF power amplifier (PA). 1.4.2.1 VCC application circuits LISA-C200 & FW75-C200 modules must be supplied through the VCC pins by one (and only one) proper DC power supply that must be one of the following: Switching regulator Low Drop-Out (LDO) linear regulator Rechargeable Li-Ion battery Primary (disposable) battery Main Supply Available? No, portable device Battery Li-Ion 3.7 V Yes, always available Main Supply Voltage >5 V? No, less than 5 V Linear LDO Regulator Yes, greater than 5 V Switching Step-Down Regulator Figure 3: VCC supply concept selection The switching step-down regulator is the typical choice when the available primary supply source has a nominal voltage much higher (e.g. greater than 5 V) than the LISA-C200 & FW75-C200 modules operating supply voltage. The use of switching step-down provides the best power efficiency for the overall application and minimizes current drawn from the main supply source. The use of an LDO linear regulator becomes convenient for a primary supply with a relatively low voltage (e.g. less than 5 V). In this case the typical 90% efficiency of the switching regulator will diminish the benefit of voltage step-down and no true advantage will be gained in input current savings. On the opposite side, linear regulators are not recommended for high voltage step-down as they will dissipate a considerable amount of energy in thermal power. If LISA-C200 & FW75-C200 modules are deployed in a mobile unit where no permanent primary supply source is available, then a battery will be required to provide VCC. A standard 3-cell Lithium-Ion battery pack directly connected to VCC is the usual choice for battery-powered devices. During charging, batteries with Ni-MH chemistry typically reach a maximum voltage that is above the maximum rating for VCC, and should therefore be avoided. The use of primary (not rechargeable) battery is uncommon, since the most cells available are seldom capable of delivering the peak current due to high internal resistance. Keep in mind that the use of batteries requires the implementation of a suitable charger circuit (not included in LISA-C200 & FW75-C200 modules). The charger circuit should be designed in order to prevent over-voltage on VCC beyond the upper limit of the absolute maximum rating. The following sections highlight some design aspects for each of the supplies listed above. CDMA-2X-11004-3 Preliminary System description Page 12 of 43 LISA-C200 & FW75-C200 - System Integration Manual Switching regulator The characteristics of the switching regulator connected to VCC pins should meet the following requirements: Power capability: the switching regulator with its output circuit must be capable of providing a voltage value to the VCC pins within the specified operating range and must be capable of delivering greater than 1.2 Amps for safe design margin Low output ripple: the switching regulator together with its output circuit must be capable of providing a clean (low noise) VCC voltage profile High switching frequency: for best performance and for smaller applications select a switching frequency ≥ 600 kHz (since L-C output filter is typically smaller for high switching frequency). The use of a switching regulator with a variable switching frequency or with a switching frequency lower than 600 kHz must be carefully evaluated since this can produce noise in the VCC voltage profile. An additional L-C low-pass filter between the switching regulator output to VCC supply pins can mitigate the ripple on VCC, but adds extra voltage drop due to resistive losses on series inductors PWM mode operation: select preferably regulators with Pulse Width Modulation (PWM) mode. While in active mode Pulse Frequency Modulation (PFM) mode and PFM/PWM mode transitions must be avoided to reduce the noise on the VCC voltage profile. Switching regulators able to switch between low ripple PWM mode and high efficiency burst or PFM mode can be used, provided the mode transition from idle mode (current consumption approximately 2 mA) to active mode (current consumption approximately 100 mA): it is permissible to use a regulator that switches from the PWM mode to the burst or PFM mode at an appropriate current threshold (e.g. 60 mA) Output voltage slope: ( not necessary for CDMA solution, ok to delete-RJC) the use of the soft start function provided by some voltage regulator must be carefully evaluated, since the voltage at the VCC pins must ramp from 2.5 V to 3.2 V within 1 ms to allow a proper switch-on of the module Figure 4 and the components listed in Table 4 show an example of a high reliability power supply circuit, where the module VCC is supplied by a step-down switching regulator capable of delivering 2.5 A current pulses with low output ripple and with fixed switching frequency in PWM mode operation greater than 1 MHz. The use of a switching regulator is suggested when the difference from the available supply rail to the VCC value is high: switching regulators provide good efficiency transforming a 12 V supply to the typical 3.8 V value of the VCC supply. 12V u-blox C200 VIN R1 RUN BD BOOST VC 10 RT C1 R2 C2 C3 C4 C5 7 PG R3 C6 SW D1 FB SYNC L1 U1 VCC L2 C7 R4 C8 C9 GND R5 11 GND Figure 4: Suggested schematic design for the VCC voltage supply application circuit using a step-down regulator CDMA-2X-11004-3 Preliminary System description Page 13 of 43 LISA-C200 & FW75-C200 - System Integration Manual Reference Description Part Number – Manufacturer C1 47 µF Capacitor Aluminum 0810 50 V MAL215371479E3 – Vishay C2 10 µF Capacitor Ceramic X7R 5750 15% 50 V C5750X7R1H106MB – TDK C3 10 nF Capacitor Ceramic X7R 0402 10% 16 V C4 680 pF Capacitor Ceramic X7R 0402 10% 16 V GRM155R71C103KA01 – Murata GRM155R71H681KA01 – Murata C5 22 pF Capacitor Ceramic COG 0402 5% 25 V GRM1555C1H220JZ01 – Murata C6 10 nF Capacitor Ceramic X7R 0402 10% 16 V GRM155R71C103KA01 – Murata C7 C8 470 nF Capacitor Ceramic X7R 0603 10% 25 V 22 µF Capacitor Ceramic X5R 1210 10% 25 V GRM188R71E474KA12 – Murata C37 330 µF Capacitor Tantalum D_SIZE 6.3 V 45 mΩ T520D337M006ATE045 - KEMET D1 Schottky Diode 40 V 3 A MBRA340T3G - ON Semiconductor L1 10 µH Inductor 744066100 30% 3.6 A 744066100 - Wurth Electronics L2 1 µH Inductor 7445601 20% 8.6 A 7445601 - Wurth Electronics R1 470 kΩ Resistor 0402 5% 0.1 W 2322-705-87474-L - Yageo R2 15 kΩ Resistor 0402 5% 0.1 W 2322-705-87153-L - Yageo R3 22 kΩ Resistor 0402 5% 0.1 W 2322-705-87223-L - Yageo R4 390 kΩ Resistor 0402 1% 0.063 W RC0402FR-07390KL - Yageo R5 100 kΩ Resistor 0402 5% 0.1 W 2322-705-70104-L - Yageo U1 Step Down Regulator MSOP10 3.5 A 2.4 MHz LT3972IMSE#PBF - Linear Technology GRM32ER61E226KE15 – Murata Table 4: Suggested components for the VCC voltage supply application circuit using a step-down regulator Low Drop-Out (LDO) linear regulator The characteristics of the LDO linear regulator connected to the VCC pins should meet the following requirements: Power capabilities: the LDO linear regulator with its output circuit must be capable of providing a proper voltage value to the VCC pins and of delivering 1.2 A Power dissipation: the power handling capability of the LDO linear regulator must be checked to limit its junction temperature to the maximum rated operating range (i.e. check the voltage drop from the max input voltage to the min output voltage to evaluate the power dissipation of the regulator) Figure 5 and the components listed in Table 5 show an example of a power supply circuit, where the VCC module supply is provided by an LDO linear regulator capable of delivering 1.2 Amps, with proper power handling capability. The use of a linear regulator is suggested when the difference from the available supply rail and the VCC value is low: linear regulators provide high efficiency when transforming a 5 V supply to the 3.6 V typical value of the VCC supply. u-blox C200 5V IN OUT VCC U1 C1 R1 R2 SHDN ADJ GND C2 R3 GND Figure 5: Suggested schematic design for the VCC voltage supply application circuit using an LDO linear regulator CDMA-2X-11004-3 Preliminary System description Page 14 of 43 LISA-C200 & FW75-C200 - System Integration Manual Reference Description Part Number - Manufacturer C1 10 µF Capacitor Ceramic X5R 0603 20% 6.3 V GRM188R60J106ME47 - Murata C2 10 µF Capacitor Ceramic X5R 0603 20% 6.3 V GRM188R60J106ME47 - Murata R1 47 kΩ Resistor 0402 5% 0.1 W RC0402JR-0747KL - Yageo Phycomp R2 4.7 kΩ Resistor 0402 5% 0.1 W RC0402JR-074K7L - Yageo Phycomp R3 2.2 kΩ Resistor 0402 5% 0.1 W RC0402JR-072K2L - Yageo Phycomp U1 LDO Linear Regulator ADJ 3.0 A LT1764AEQ#PBF - Linear Technology Table 5: Suggested components for VCC voltage supply application circuit using an LDO linear regulator Rechargeable Li-Ion battery Rechargeable Li-Ion batteries connected to the VCC pins should meet the following requirements: Maximum pulse and DC discharge current: the rechargeable Li-Ion battery with its output circuit must be capable of delivering 1.2 A to the VCC pins and must be capable of delivering a DC current greater than the module maximum average current consumption to VCC pins. The maximum pulse discharge current and the maximum DC discharge current are not always reported in battery data sheets, but the maximum DC discharge current is typically almost equal to the battery capacity in Amp-hours divided by 1 hour DC series resistance: the rechargeable Li-Ion battery with its output circuit must be capable of avoiding a VCC voltage drop greater than 250 mV during peak currents (Max Tx Power). Primary (disposable) battery The characteristics of a primary (non-rechargeable) battery connected to VCC pins should meet the following requirements: Maximum pulse and DC discharge current: the non-rechargeable battery with its output circuit must be capable of delivering 1.2 A to the VCC pins and must be capable of delivering a DC current greater than the module maximum average current consumption at the VCC pins. The maximum pulse and the maximum DC discharge current is not always reported in battery data sheets, but the maximum DC discharge current is typically almost equal to the battery capacity in Amp-hours divided by 1 hour DC series resistance: the non-rechargeable battery with its output circuit must be capable of avoiding a VCC voltage drop greater than 250 mV during peak currents (Max Tx Power). Additional recommendations for the VCC supply application circuits To reduce voltage drops, use a low impedance power source. The resistance of the power supply lines (connected to the VCC and GND pins of the module) on the application board and battery pack should also be considered and minimized: cabling and routing must be as short as possible in order to minimize power losses. Three3 or five4 pins are allocated for VCC supply. Another seven pins are designated for GND connection. Even if all the VCC pins and all the GND pins are internally connected within the module, it is recommended to properly connect all of them to supply the module in order to minimize series resistance losses. The placement ceramic capacitors on the VCC line on the main board close to the connector will benefit operation. To reduce voltage ripple and noise, place the following near the VCC pins: 100 nF capacitor (e.g Murata GRM155R61A104K) to filter digital logic noise from clocks and data sources 22 µF capacitor (e.g. Murata GRM31CR60J226K) to supply local DC energy. Figure 6 shows the complete configuration but the mounting of each single component depends on the application design. LISA-C200. FW75.

This ranges from continuous high current drawn in CDMA connected mode, to the low current consumption during in idle mode. 1.4.3.1 CDMA connected mode During a CDMA connection, the module can transmit and receive continuously due to the Frequency Division Duplex (FDD) mode of operation with the Code Division Multiple Access (CDMA). The current consumption depends again on output RF power, which is always regulated by network commands. These power control commands are logically divided into a slot of 1.25 ms, thus the rate of power change can reach a maximum rate of 800 Hz. Since transmission and reception are continuously enabled due to FDD CDMA implemented in the 3G that differs from the TDMA implemented in the 2G case. In the worst scenario, corresponding to a continuous transmission and reception at maximum output power (approximately 250 mW or 24 dBm), the current dra wn by the module at the VCC pins is in the order of continuous 600-700 mA. Even at lowest output RF power (approximately 0.01 µW or -50 dBm), the current is in the order of less than 100 mA due to module baseband processing and transceiver activity. An example of current consumption profile of the data module in CDMA continuous transmission mode is shown in Figure 7.

Alternatively, at higher data rates the transmitted power is likely to increase due to the higher quality signal required by the network to cope with enhanced data speed. CDMA-2X-11004-3 Preliminary System description Page 17 of 43 LISA-C200 & FW75-C200 - System Integration Manual 1.5 System functions 1.5.1 Module power on The module power on sequence is initiated in one of these ways: Rising edge on the VCC pin to a valid voltage for module supply AND if the PWR_ON pin is permanently low when VCC is applied Falling edge on the PWR_ON pin (pin must be held low for >150 msec) Name Description Remarks PWR_ON Power on input PWR_ON pin has internal pull up resistor. Recommended to use open collector or drain configuration to pull down. Table 7: Power on pin The PWR_ON pin ESD sensitivity rating is 1 kV (Human Body Model according to JESD22-A114F). Higher protection level could be required if the line is externally accessible on the application board. Higher protection level can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor array) on the line connected to this pin. 1.5.1.1 Rising edge on VCC \When a supply is connected to VCC pins, the module supply supervision circuit controls the subsequent activation of the power up state machines: the module is switched on when the voltage rises up to the VCC operating range minimum limit (3.4 V) starting from a voltage value lower than 2.25 V (See LISA-C200 Data Sheet [1] or the FW75-C200 Data Sheet [2]), provided that the PWR_ON pin is permanently low when VCC is applied. 1.5.1.2 Falling edge on PWR_ON The module power on sequence starts when a falling edge is forced on the PWR_ON input pin. After applying a falling edge, it is suggested to hold a low level on the PWR_ON signal for at least 300 ms to properly switch on the module. The electrical characteristics of the PWR_ON input pin are different from the other digital I/O interfaces: the high and the low logic levels have different operating ranges and the pin is not-tolerant to voltages up to the battery voltage. The detailed electrical characteristics are described in the LISA-C200 Data Sheet [1] or the FW75-C200 Data Sheet [2]. Once the module has been turned on, PWR_ON pin has no effect. On the other hand it makes no sense to keep this pin low once the module has been turned on: if the pin is kept low it will draw unnecessary current. Following are some typical examples of application circuits to turn the module on using the PWR_ON input pin. The simplest way to turn on the module is to use a push button that shorts the PWR_ON pin to ground. If the PWR_ON input is connected to an external device (e.g. application processor), it is suggested to use an open drain output on the external device.

Then, the proper way to switch off the module is by means of the AT+CPWROFF command. When the module is in power-off mode, i.e. the AT+CPWROFF command has been sent and a voltage value within the operating range limits is still provided to the VCC pin, the digital inputoutput pads of the baseband chipset (i.e. all the digital pins of the module) are locked in tri-state (i.e. floating). The power down tri-state function isolates the module pins from its environment, when no proper operation of the outputs can be guaranteed. The module can be switched on from power-off mode by forcing a proper start-up event (i.e. a falling edge on the PWR_ON pin). After the detection of a start-up event, all the digital pins of the module are held in tri-state until all the internal LDO voltage regulators are turned on in a defined power-on sequence. Then, as described in Datasheet the baseband core is still held in reset state for a time interval: the internal reset signal (which is not available on a module pin) is still low and any signal from the module digital interfaces is held in reset state. The reset state of all the digital pins is reported in the pin description table of the LISA-C200 Data Sheet [1] or the FW75-C200 Data Sheet [2]. When the internal signal is released, the configuration of the module interfaces starts: during this phase any digital pin is set in a proper sequence from the reset state to the default operational configuration. Finally, the module is fully ready to operate when all interfaces are configured. The Internal Reset signal is not available on a module pin. CDMA-2X-11004-3 Preliminary System description Page 19 of 43 LISA-C200 & FW75-C200 - System Integration Manual 1.5.2 Module power off The correct way to switch off LISA-C200 & FW75-C200 modules is by means of +CPWROFF AT command (more details in u-blox C200 AT Commands Manual [3]): in this way the current parameter settings are saved in the module’s non-volatile memory and a proper network detach is performed. An under-voltage shutdown will be done if the VCC supply is removed, but in this case the current parameter settings are not saved in the module’s non-volatile memory and a proper network detach cannot be performed. 1.5.3 Module reset The module reset can be performed: Forcing a low level on the RESET_N input pin, causing an “external” or “hardware” reset (LISA-C200 only) AT+CFUN command (more details in u-blox C200 AT Commands Manual [3]): in this case an “internal” or “software” reset is performed, causing an asynchronous reset of the baseband processor 1.6 RF connection The ANT connector has 50 nominal characteristic impedance and must be connected to the antenna through a 50 transmission line to allow transmission and reception of radio frequency (RF) signals in the Cell and PCS operating bands. Name Description Remarks ANT FW75 LISA-C200 RF connector Zo = 50 nominal characteristic impedance. U.FL connector Surface Mount pad Table 9: Antenna connector The ANT port ESD immunity rating is 500 V (according to IEC 61000-4-2). Higher protection level could be required if the line is externally accessible on the application board. Choose an antenna with optimal radiating characteristics for the best electrical performance and overall module functionality. Focus on minimizing the insertion loss between radiating antenna and the module RF connector. Overall system performance depends on antenna reception and transmission. See section 2.4 for further details regarding antenna guidelines.

One full-speed USB 2.0 compliant interface, with maximum data rate of 12 Mb/s. Only one interface is active. Default is USB, if no USB is detected then it is assumed that the UART interface is desired. LISA-C200 & FW75-C200 modules are designed to operate as a CDMA wireless modem, which represents the data circuit-terminating equipment (DCE) as described by the ITU-T V.24 Recommendation [4]. A customer application processor connected to the module through one of the interfaces represents the data terminal equipment (DTE). All the interfaces listed above are controlled and operated with: Sprint required AT Commands Verizon required AT Commands AT commands according to 3GPP TS 27.010 [7] AT commands according to 3GPP TS 27.005 [6] AT commands according to 3GPP TS 27.010 u-blox AT commands For the complete list of supported AT commands and their syntax refer to the u-blox C200 AT Commands Manual [3]. The USB interface, using all the lines provided (VUSB_DET, USB_D+ and USB_D-), can be used for firmware upgrade: To directly enable PC (or similar) connection to the module for firmware upgrade, provide direct access on the application board to the VUSB_DET, USB_D+ and USB_D- lines of the module . Also provide access to the PWR_ON & HW_SHUTDOWN pins, or enable the DC supply connected to the VCC pin to start the module firmware upgrade The following sub-chapters describe serial interface configuration and provide a detailed description of each interface for the application circuits. 1.7.1 Serial interfaces configuration UART and USB serial interfaces are available as AT command interface and for Packet-Switched Data communication. The serial interfaces are configured as described in Table 10 (for information about further settings, please refer to the u-blox C200 AT Commands Manual [3]). Note : The UART is 5 wire implementation therefore DTR, DSR and DCD functions are not available.

UART interface provides RS-232 functionality conforming to the ITU-T V.24 Recommendation (more details available in ITU Recommendation [4]), with CMOS compatible signal levels: 0 V for low data bit or ON state, and 2.8 V for high data bit or OFF state. One external voltage translators (e.g. Maxim MAX13234E) could be used to provide RS-232 (5 lines) compatible signal levels. This chip translates the voltage levels from 1.8 V (module side) to the RS-232 standard. For detailed electrical characteristics refer to LISA-C200 Data Sheet [1] or the FW75C200 Data Sheet [2]. FW75-C200 logic levels are 2.8 V interface. LISA-C200 logic levels are 1.8 V interface. The LISA-C200 & FW75-C200 modules are designed to operate as a CDMA wireless modem, which represents the data circuit-terminating equipment (DCE) as described by the ITU-T V.24 Recommendation [4]. A customer application processor connected to the module through the UART interface represents the data terminal equipment (DTE).

Higher protection level could be required if the lines are externally accessible on the application board. Higher protection level can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor array) on the lines connected to these pins. UART application circuits Providing the TxD, RxD, RI, RTS and CTS lines only (not using the complete V.24 link) Modem DSR, DCD and DTR lines is not available in the application, the application circuit described in Figure 9 must be implemented: u-blox C200 (DCE) Application Processor (DTE) TxD RxD RTS CTS 0Ω TP 0Ω TP 0Ω TP 0Ω TP TXD RXD RTS CTS DTR DSR RI RI DCD GND GND Figure 9: UART interface application circuit with partial V.24 link (5-wire) in the DTE/DCE serial communication Additional considerations If the module USB interface is connected to the application processor, testpoints can be added on the lines to accommodate the access and a 0 Ω series resistor must be mounted on each line to detach the module pin from any other connected device. Otherwise, if the USB interface is not connected to the application processor, it is highly recommended to provide direct access to VUSB_DET, USB_D+, USB_D- lines for execution of firmware upgrade over USB and for debug purpose. In both cases, provide as well access to RESET_N pin, or to the PWR_ON pin, or enable the DC supply connected to the VCC pin to start the module firmware upgrade. CDMA-2X-11004-3 Preliminary System description Page 23 of 43 LISA-C200 & FW75-C200 - System Integration Manual 1.7.3 USB interface LISA-C200 & FW75-C200 modules provide a full-speed USB interface at 12 Mb/s compliant with the Universal Serial Bus Revision 2.0 specification [9]. It acts as a USB device and can be connected to any USB host such as a PC or other Application Processor. The USB-device shall look for all upper-SW-layers like any other serial device. This means that LISA-C200 & FW75-C200 modules emulate all serial control logical lines. If the logical DTR line isn't enabled by the USB host, the module doesn’t answer to AT commands by the USB interface. Name Description Remarks VUSB_DET USB detect input Apply 5 V typical to enable USB USB_D+ USB Data Line D+ 90 Ω nominal differential impedance. Pull-up or pull-down resistors and external series resistors as required by the USB 2.0 high-speed specification [9] are part of the USB pad driver and need not be provided externally. USB_D- USB Data Line D- 90 Ω nominal differential impedance. Pull-up or pull-down resistors and external series resistors as required by the USB 2.0 high-speed specification [9] are part of the USB pad driver and need not be provided externally. Table 12: USB pins The USB interface pins ESD sensitivity rating is 1 kV (Human Body Model according to JESD22-A114F). Higher protection level could be required if the lines are externally accessible on the application board. Higher protection level can be achieved by mounting a very low capacitance (i.e. less or equal to 1 pF) ESD protection (e.g. Tyco Electronics PESD0402-140 ESD protection device) on the lines connected to these pins. LISA-C200 & FW75-C200 module identifies itself by its VID (Vendor ID) and PID (Product ID) combination, included in the USB device descriptor. VID and PID of LISA-C200 & FW75-C200 modules are the following: VID = 0x1546 PID = 0x1121 1.7.3.1 USB application circuit Since the module acts as a USB device, the USB supply (5.0 V typ.) must be provided to VUSB_DET by the connected USB host. The USB interface is enabled only when a valid voltage as USB supply is detected by the VUSB_DET input. Neither the USB interface, nor the whole module is supplied by the VUSB_DET input: the VUSB_DET senses the USB supply voltage and absorbs few microamperes. The USB_D+ and USB_D- lines carry the USB serial data and signaling. The lines are used in single ended mode for relatively low speed signaling handshake, as well as in differential mode for fast signaling and data transfer. USB pull-up or pull-down resistors on pins USB_D+ and USB_D- as required by the Universal Serial Bus Revision 2.0 specification [9] are part of the USB pad driver and do not need to be externally provided. External series resistors on pins USB_D+ and USB_D- as required by the Universal Serial Bus Revision 2.0 specification [9] are also integrated: characteristic impedance of USB_D+ and USB_D- lines is specified by the USB standard. The most important parameter is the differential characteristic impedance applicable for odd-mode electromagnetic field, which should be as close as possible to 90 differential: signal integrity may be degraded if the PCB layout is not optimal, especially when the USB signaling lines are very long.

The USB interface doesn’t support the multiplexer protocol. This is a data link protocol (layer 2 of OSI model) which uses HDLC-like framing and operates between the module (DCE) and the application processor (DTE) and allows a number of simultaneous sessions over the UART: the user can concurrently use AT command interface on one MUX channel and Packet-Switched Data communication on another MUX channel.. Each session consists of a stream of bytes transferring various kinds of data such as SMS, PSD, AT commands in general. This permits, for example, SMS to be transferred to the DTE when a data connection is in progress.

CDMA-2X-11004-3 Preliminary System description Page 27 of 43 LISA-C200 & FW75-C200 - System Integration Manual 2 Design-In 2.1 Design-in checklist 2.1.1 Schematic checklist The following are the most important points for a simple schematic check: DC supply must provide a nominal voltage at VCC pin above the minimum operating range limit. VCC supply should be clean, with very low ripple/noise: suggested passive filtering parts can be inserted. Provide appropriate access to USB interface and/or to UART RxD, TxD, CTS, RTS lines for debugging. Insert the suggested passive filtering parts on each used analog audio line. Check 50 nominal characteristic impedance of the RF transmission line connected to ANT coax connector or Printed Circuit Board 50 transmission line impedance for LISA-C200 Follow the recommendations of the antenna producer for correct antenna installation and deployment. DC supply must be capable of supporting 1.2 A, providing a voltage at VCC pin above the minimum operating range limit and with a maximum 250 mV voltage drop from the nominal value. Connect only one DC supply to VCC: different DC supply systems are mutually exclusive. Don’t apply loads which might exceed the limit for maximum available current from V_INT supply. Check that voltage level of any connected pin does not exceed the relative operating range. Capacitance and series resistance must be limited on each SIM signal to match the SIM specifications. Insert the suggested low capacitance ESD protection and passive filtering parts on each SIM signal. Check UART signals direction, since the signal names follow the ITU-T V.24 Recommendation [4]. Provide appropriate access to USB interface and/or to UART RxD, TxD lines and access to PWR_ON and/or HW_SHUTDOWN lines on the application board in order to flash/upgrade the module firmware. Add a proper pull-up resistor to a proper supply on each DDC (I2C) interface line, if the interface is used. Capacitance and series resistance must be limited on each line of the DDC interface. Use transistors with at least an integrated resistor in the base pin or otherwise put a 10 kΩ resistor on the board in series to the GPIO when those are used to drive LEDs. Provide proper precautions for ESD immunity as required on the application board. All unused pins can be left floating on the application board Layout checklist The following are the most important points for a simple layout check: Ensure no coupling occurs with other noisy or sensitive signals (primarily SIM signals). VCC line should be wide and short. Ensure proper grounding. Consider “No-routing” areas for the Data Module footprint. Optimize placement for minimum length of RF line and closer path from DC source for VCC. Design USB_D+ / USB_D- connection as 90 differential pair. 2.1.2 Antenna checklist Antenna should have 50 impedance, V.S.W.R less then 3:1, recommended 2:1 on operating bands in deployment geographical area. Follow the recommendations of the antenna producer for correct antenna installation and deployment (PCB layout and matching circuitry).

See 1: FW75-C200 : LISA-C200 Table 17 for a list of pins ranked by their importance in layout design. See the LISA-C200 Data Sheet [1] or the FW75 Data Sheet [2] for the complete pin lists.

Antenna radiating performance has direct impact on the reliability of connections over the Air Interface. A bad termination of ANT can result in poor performance of the module. The following parameters should be checked: Item Recommendations Impedance 50 Ω nominal characteristic impedance Frequency Range Depends on the Mobile Network used. LISA-C200: - Cell Band B0: 824..894 MHz - PCS Band B1 B2: 1850..1990 MHz Input Power V.S.W.R >2 W peak <2:1 recommended, <3:1 acceptable Return Loss S11<-10 dB recommended, S11<-6 dB acceptable Gain <3 dBi Table 18: General recommendation for CDMA antenna To preserve the original u-blox FCC ID, antenna gain shall remain below 3 dBi. CDMA antennas are typically available as: Linear monopole: typical for fixed applications. The antenna extends mostly as a linear element with a dimension comparable to lambda/4 of the lowest frequency of the operating band. Magnetic base may be available. Cable or direct RF connectors are common options. The integration normally requires the fulfillment of some minimum guidelines suggested by antenna manufacturer Patch-like antenna: better suited for integration in compact designs (e.g. mobile phone). These are mostly custom designs where the exact definition of the PCB and product mechanical design is fundamental for tuning of antenna characteristics For integration observe these recommendations: Ensure 50 Ω antenna termination by minimizing the V.S.W.R. or return loss, as this will optimize the electrical performance of the module. See section 2.4.1 Select antenna with best radiating performance. See section 2.4.2 If a cable is used to connect the antenna radiating element to application board, select a short cable with minimum insertion loss. The higher the additional insertion loss due to low quality or long cable, the lower the connectivity Follow the recommendations of the antenna manufacturer for correct installation and deployment Do not include antenna within closed metal case Do not place antenna in close vicinity to end user since the emitted radiation in human tissue is limited by S.A.R. regulatory requirements Do not use directivity antenna since the electromagnetic field radiation intensity is limited in some countries Take care of interaction between co-located RF systems since the RF transmitted power may interact or disturb the performance of companion systems Place antenna far from sensitive analog systems or employ countermeasures to reduce electromagnetic compatibility issues that may arise CDMA-2X-11004-3 Preliminary Design-In Page 32 of 43 LISA-C200 & FW75-C200 - System Integration Manual 2.4.1 Antenna termination The LISA-C200 & FW75-C200 modules are designed to work on a 50 load. However, real antennas have no perfect 50 load on all the supported frequency bands. Therefore, to reduce as much as possible performance degradation due to antenna mismatch, the following requirements should be met: Measure the antenna termination with a network analyzer: connect the antenna through a coaxial cable to the measurement device, the |S11| indicates which portion of the power is delivered to antenna and which portion is reflected by the antenna back to the module output. A good antenna should have an |S11| below -10 dB over the entire frequency band. Due to miniaturization, mechanical constraints and other design issues, this value will not be achieved. An |S 11| value of about -6 dB – (in the worst case) - is acceptable. Figure 15 shows an example of this measurement: Figure 15: |S11| sample measurement of a penta-band antenna that covers in a small form factor the 4 bands (850 MHz, 900 MHz, 1800 MHz and 1900 MHz) Figure 16 shows comparable measurements performed on a wideband antenna. The termination is better, but the size of the antenna is considerably larger. Figure 16: |S11| sample measurement of a wideband antenna CDMA-2X-11004-3 Preliminary Design-In Page 33 of 43 LISA-C200 & FW75-C200 - System Integration Manual 2.4.2 Antenna radiation An indication of the antenna’s radiated power can be approximated by measuring the |S 21| from a target antenna to the measurement antenna, using a network analyzer with a wideband antenna. Measurements should be done at a fixed distance and orientation, and results compared to measurements performed on a known good antenna. Figure 17 through Figure 18 show measurement results. A wideband log periodic-like antenna was used, and the comparison was done with a half lambda dipole tuned at 900 MHz frequency. The measurements show both the |S11| and |S21| for the penta-band internal antenna and for the wideband antenna. Figure 17: |S11| and |S21| comparison between a 900 MHz tuned half wavelength dipole (green/purple) and a penta-band internal antenna (yellow/cyan) The half lambda dipole tuned at 900 MHz is known and has good radiation performance (both for gain and directivity). Then, by comparing the |S 21| measurement with antenna under investigation for the frequency where the half dipole is tuned (e.g. marker 3 in Figure 17) it is possible to make a judgment on the antenna under test: if the performance is similar then the target antenna is good. Figure 18: |S11| and |S21| comparison between a 900 MHz tuned half wavelength dipole (green/purple) and a wideband commercial antenna (yellow/cyan) Instead if |S21| values for the tuned dipole are much better than the antenna under evaluation (like for marker 1/2 area of Figure 18, where dipole is 5 dB better), then it can be argued that the radiation of the target antenna (the wideband dipole in this case) is considerably less. The same procedure should be repeated on other bands with half wavelength dipole re-tuned to the band under investigation. CDMA-2X-11004-3 Preliminary Design-In Page 34 of 43 LISA-C200 & FW75-C200 - System Integration Manual For good antenna radiation performance, antenna dimensions should be comparable to a quarter of the wavelength. Different antenna types can be used for the module, many of them (e.g. patch antennas, monopole) are based on a resonating element that works in combination with a ground plane. The ground plane, ideally infinite, can be reduced down to a minimum size that must be similar to one quarter of the wavelength of the minimum frequency that has to be radiated (transmitted/received). Numerical sample: frequency = 1 GHz wavelength = 30 cm minimum ground plane (or antenna size) = 7.5 cm. Below this size, the antenna efficiency is reduced. 2.5 ESD immunity test precautions The immunity of the device (i.e. the application board where LISA-C200 & FW75-C200 module is mounted) Electrostatic Discharge must be certified in compliance to the testing requirements standard [12], and the requirements for radio and digital cellular radio telecommunications system equipment standards [12] and [14]. The ESD test is performed at the enclosure port referred to as the physical boundary through which the EM field radiates. If the device implements an integral antenna, the enclosure port is seen as all insulating and conductive surfaces housing the device. If the device implements a removable antenna, the antenna port can be separated from the enclosure port. The antenna port comprises the antenna element and its interconnecting cable surfaces. The applicability of the ESD test depends on the device classification, as well the test on other ports or on interconnecting cables to auxiliary equipments depends to the device accessible interfaces and manufacturer requirements. Contact discharges are performed at conductive surfaces whereas air discharges are performed on insulating surfaces. Indirect contact discharges are performed on the measurement setup horizontal and vertical coupling planes. Implement the following precautions to satisfy ESD immunity test requirements performed at the device enclosure in compliance to the category level and shown in the following table. Application Category Immunity Level All exposed surfaces of the radio equipment and ancillary equipment in a representative configuration Contact Discharge 4 kV Air Discharge 8 kV Table 19: Electromagnetic Compatibility (EMC) ESD immunity requirement, standards “EN 61000-4-2, EN 301 489-1 V1.8.1, EN 301 489-7 V1.3.1” Although EMC certification (including ESD immunity testing) must be performed in the final application of the radio equipment EUT, results are provided for LISA modules performing the test with a representative configuration to show that requirements can be met. Since an external antenna is used, the antenna port can be separated from the enclosure port. The reference application is not enclosed in a box so the enclosure port is not indentified with physical surfaces. Therefore, some test cases cannot be applied. Only the antenna port is identified as accessible for direct ESD exposure. The reference application implements all precautions described in the sections below. ESD immunity test results and applicability are reported in Table 20 according to test requirements [12], [12] and [14].

The following precautions are suggested: HW_SHUTDOWN pin (FW75-C200 only) Sensitive interface is the reset line (HW_SHUTDOWN pin): A 47 pF bypass capacitor (e.g. Murata GRM1555C1H470JA01) have to be mounted on the line termination connected to the HW_SHUTDOWN pin to avoid a module reset caused by an electrostatic discharge applied to the application board enclosure A series ferrite bead (e.g. Murata BLM15HD182SN1) must be added on the line connected to the HW_SHUTDOWN pin to avoid a module reset caused by an electrostatic discharge applied to the application board enclosure It is recommended to keep the connection line to HW_SHUTDOWN as short as possible Reset_N pin (LISA-C200 only) Sensitive interface is the reset line (Reset_N pin): A 47 pF bypass capacitor (e.g. Murata GRM1555C1H470JA01) have to be mounted on the line termination connected to the Reset_N pin to avoid a module reset caused by an electrostatic discharge applied to the application board enclosure A series ferrite bead (e.g. Murata BLM15HD182SN1) must be added on the line connected to the Reset_N pin to avoid a module reset caused by an electrostatic discharge applied to the application board enclosure It is recommended to keep the connection line to Reset_N as short as possible LISA mounted on application design: Not Applicability -> EUT with insulating enclosure surface, EUT without enclosure surface Applicability -> EUT with conductive enclosure surface LISA mounted on application design: Not Applicability -> Antenna with insulating surface Applicability -> Antenna with conductive surface LISA mounted on application design: Applicability -> EUT with insulating enclosure surface Not Applicability -> EUT with conductive enclosure surface, EUT without enclosure surface CDMA-2X-11004-3 Preliminary Design-In Page 36 of 43 LISA-C200 & FW75-C200 - System Integration Manual u-blox C200 Reset push button FB1 HW_SHUTDOWN ESD C1 Application Processor u-blox C200 Open Drain Output FB2 HW_SHUTDOWN C2 Figure 19: HW_SHUTDOWN application circuits for ESD immunity test Reference Description Remarks ESD Varistor for ESD protection.

Antenna precaution suggestions are provided: If the device implements an embedded antenna and the device insulating enclosure avoids air discharge up to +8 kV / -8 kV to the antenna interface, no further precautions to ESD immunity test should be needed If the device implements an external antenna and the antenna and its connecting cable are provided with a completely insulating enclosure to avoid air discharge up to +8 kV / -8 kV to the whole antenna and cable surfaces, no further precautions to ESD immunity test should be needed CDMA-2X-11004-3 Preliminary Design-In Page 37 of 43 LISA-C200 & FW75-C200 - System Integration Manual If the device implements an external antenna and the antenna or its connecting cable are not provided with completely insulating enclosure to avoid air discharge up to +8 kV / -8 kV to the whole antenna and cable surfaces, the following precautions to ESD immunity test should be implemented on the application board A higher protection level is required at the ANT port if the line is externally accessible on the application board. ESD immunity test requires protection up to +4 kV / -4 kV for direct Contact Discharge and up to +8 kV / -8 kV for Air Discharge applied to the antenna port. 2.5.3 Module interfaces precautions All the module pins that are externally accessible should be included in the ESD immunity test since they are considered to be a port as defined in [12]. Depending on applicability, and in order to satisfy ESD immunity test requirements and ESD category level, pins connected to the port should be protected up to +4 kV / -4 kV for direct Contact Discharge, and up to +8 kV / -8 kV for Air Discharge applied to the enclosure surface. The maximum ESD sensitivity rating of all the pins of the module, except the ANT pin, is 1 kV (Human Body Model according to JESD22-A114F). A higher protection level can be achieved by mounting an ESD protection (e.g. EPCOS CA05P4S14THSG varistor array or CT0402S14AHSG). For the USB interface a very low capacitance (i.e. less or equal to 1 pF) ESD protection (e.g. Tyco Electronics PESD0402-140 ESD protection device) can be mounted on the lines connected to USB_D+ and USB_D- pins. For the SIM interface a low capacitance (i.e. less than 10 pF) ESD protection (e.g. Infineon ESD8V0L2B-03L or AVX USB0002) must be placed near the SIM card holder on each line (VSIM, SIM_IO, SIM_CLK, SIM_RST).
