Product Technical SpecificationRev 3 Aug.17 18 41110251Power SupplyThe host provides power to the MC7475 through multiple power and ground pins as summarized in Table 3-2.The host must provide safe and continuous power at all times; the module does not have an independent power supply, or protection circuits to guard against electrical issues.USB InterfaceImportant: Host support for USB 2.0 signals is required.The device supports a USB 2.0 interface for communication between the host and module.The interface complies with the [7] Universal Serial Bus Specification, Rev 2.0, and the host device must be designed to the same standards (subject to details shown in Table 3-3 below). (Note: When designing the host device, careful PCB layout practices must be followed.)USB Throughput PerformanceThis device has been designed to achieve optimal performance and maximum throughput using USB high-speed mode (USB 2.0). Although the device may operate with a high speed host, throughput performance will be on an “as is” c. Signal directions are from module’s point of view (e.g. ‘Output’ from module to host, ‘Input’ to module from host.)d. To avoid adverse effects on module operation, do not draw more than 10 mA current on pin 11.e. The module must not be plugged into a port that supports PCI Express—the pin is used by a PCIE signal, which can cause the module to be in reset state or occasionally reset.f.

Each SIM holds information for a unique account, allowing users to optimize their use of each account on multiple devices.The SIM pins (Table 3-4) provide the connections necessary to interface to SIM sockets located on the host device as shown in Figure 3-2 on page 20.

Electrical SpecificationsRev 3 Aug.17 21 41110251SIM ImplementationNote: For interface design requirements, refer to ETSI TS 102 230 V5.5.0, section 5.2.When designing the remote SIM interface, you must make sure that SIM signal integrity is not compromised.Some design recommendations include:•Total impedance of the VCC and GND connections to the SIM, measured at the module connector, should be less than 1  to minimize voltage drop (includes any trace impedance and lumped element components—inductors, filters, etc.).•Position the SIM connector 10 cm from the module. If a longer distance is required because of the host device design, use a shielded wire assembly—connect one end as close as possible to the SIM connector and the other end as close as possible to the module connector. The shielded assembly may help shield the SIM interface from system noise.•Avoid routing the clock and data lines for each SIM (USIM_CLK/USIM_DATA, USIM2_CLK/USIM2_DATA) in parallel over distances 2 cm—cross-coupling of a clock and data line pair can cause failures.•3GPP has stringent requirements for I/O rise time (<1 µs), signal level limits, and noise immunity—consider this carefully when developing your PCB layout.·Keep signal rise time <1 µs—keep SIM signals as short as possible, and keep very low capacitance traces on the data and clock signals (USIM_CLK, USIM_DATA, USIM2_CLK, USIM2_DATA). High capacitance increases signal rise time, potentially causing your device to fail certification tests.•Add external pull-up resistors (15 k–30 k), if required, between the data and power lines for each SIM (USIM_DATA/USIM_PWR, USIM2_DATA/USIM2_PWR) to optimize the signal rise time.•VCC line should be decoupled close to the SIM socket.•SIM is specified to run up to 5 MHz (SIM clock rate). Take note of this speed in the placement and routing of the SIM signals and connectors.•You must decide whether additional ESD protection is required for your product, as it is dependent on the application, mechanical enclosure, and SIM connector design. The SIM pins will require additional ESD protection if they are exposed to high ESD levels (i.e. can be touched by a user).•Putting optional decoupling capacitors on the SIM power lines (USIM_PWR, USIM2_PWR) near the SIM sockets is recommended—the longer the trace length (impedance) from the socket to the module, the greater the capaci-tance requirement to meet compliance tests.•Putting an optional series capacitor and resistor termination (to ground) on the clock lines (USIM_CLK, USIM2_CLK) at the SIM sockets to reduce EMI and increase signal integrity is recommended if the trace length between the SIM socket and module is long—47 pF and 50  resistor are recommended.•Test your first prototype host hardware with a Comprion IT3 SIM test device at a suitable testing facility.

RF SpecificationsRev 3 Aug.17 25 41110251Antenna and CablingWhen selecting the antenna and cable, it is critical to RF performance to optimize antenna gain and cable loss.Note: For detailed electrical performance criteria, see Appendix 8: Antenna Specification on page 43.Choosing the Correct Antenna and CablingWhen matching antennas and cabling:•The antenna (and associated circuitry) should have a nominal impedance of 50  with a recommended return loss of better than 10 dB across each frequency band of operation.•The system gain value affects both radiated power and regulatory (FCC) test results.Designing Custom AntennasConsider the following points when designing custom antennas:•A skilled RF engineer should do the development to ensure that the RF performance is maintained.•If both CDMA and UMTS modules will be installed in the same platform, you may want to develop separate antennas for maximum performance.Determining the Antenna’s LocationWhen deciding where to put the antennas:•Antenna location may affect RF performance. Although the module is shielded to prevent interference in most applications, the placement of the antenna is still very important—if the host device is insufficiently shielded, high levels of broadband noise or spurious interference can degrade the module’s performance.•Connecting cables between the module and the antenna must have 50  impedance. If the impedance of the module is mismatched, RF performance is reduced significantly.•Antenna cables should be routed, if possible, away from noise sources (switching power supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna. See Interference From Other Wireless Devices on page 26.Ground ConnectionWhen connecting the module to system ground:•Prevent noise leakage by establishing a very good ground connection to the module through the host connector.•Connect to system ground using the two mounting holes at the top of the module (shown in Figure 4-1 on page 24).•Minimize ground noise leakage into the RF.Depending on the host board design, noise could potentially be coupled to
Product Technical SpecificationRev 3 Aug.17 26 41110251the module from the host board. This is mainly an issue for host designs that have signals traveling along the length of the module, or circuitry operating at both ends of the module interconnects.Interference and SensitivitySeveral interference sources can affect the module’s RF performance (RF desense). Common sources include power supply noise and device-generated RF.RF desense can be addressed through a combination of mitigation techniques (Methods to Mitigate Decreased Rx Performance on page 27) and radiated sensitivity measurement (Radiated Sensitivity Measurement on page 27).Interference From Other Wireless DevicesWireless devices operating inside the host device can cause interference that affects the module.To determine the most suitable locations for antennas on your host device, evaluate each wireless device’s radio system, considering the following:•Any harmonics, sub-harmonics, or cross-products of signals generated by wireless devices that fall in the module’s Rx range may cause spurious response, resulting in decreased Rx performance.•The Tx power and corresponding broadband noise of other wireless devices may overload or increase the noise floor of the module’s receiver, resulting in Rx desense.The severity of this interference depends on the closeness of the other antennas to the module’s antenna. To determine suitable locations for each wireless device’s antenna, thoroughly evaluate your host device’s design.Host-generated RF InterferenceAll electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module.Proximity of host electronics to the antenna in wireless devices can contribute to decreased Rx performance. Components that are most likely to cause this include:•Microprocessor and memory•Display panel and display drivers•Switching-mode power suppliesDevice-generated RF InterferenceThe module can cause interference with other devices. Wireless devices such as AirPrime embedded modules transmit in bursts (pulse transients) for set durations (RF burst frequencies). Hearing aids and speakers convert these burst frequencies into audible frequencies, resulting in audible noise.
RF SpecificationsRev 3 Aug.17 27 41110251Methods to Mitigate Decreased Rx PerformanceIt is important to investigate sources of localized interference early in the design cycle. To reduce the effect of device-generated RF on Rx performance:•Put the antenna as far as possible from sources of interference. The drawback is that the module may be less convenient to use.•Shield the host device. The module itself is well shielded to avoid external interference. However, the antenna cannot be shielded for obvious reasons. In most instances, it is necessary to employ shielding on the components of the host device (such as the main processor and parallel bus) that have the highest RF emissions. •Filter out unwanted high-order harmonic energy by using discrete filtering on low frequency lines.•Form shielding layers around high-speed clock traces by using multi-layer PCBs.•Route antenna cables away from noise sources.Radiated Spurious Emissions (RSE)When designing an antenna for use with AirPrime embedded modules, the host device with an AirPrime embedded module must satisfy any applicable standards/local regulatory bodies for radiated spurious emission (RSE) for receive-only mode and for transmit mode (transmitter is operating).Note that antenna impedance affects radiated emissions, which must be compared against the conducted 50-ohm emissions baseline. (AirPrime embedded modules meet the 50-ohm conducted emissions requirement.)Radiated Sensitivity MeasurementA wireless host device contains many noise sources that contribute to a reduction in Rx performance.To determine the extent of any receiver performance desensitization due to self-generated noise in the host device, over-the-air (OTA) or radiated testing is required. This testing can be performed by Sierra Wireless or you can use your own OTA test chamber for in-house testing.Sierra Wireless’ Sensitivity Testing and Desensitization InvestigationAlthough AirPrime embedded modules are designed to meet network operator requirements for receiver performance, they are still susceptible to various performance inhibitors.As part of the Engineering Services package, Sierra Wireless offers modem OTA sensitivity testing and desensitization (desense) investigation.

Antenna SpecificationRev 3 Aug.17 45 41110251Recommended GPS Antenna SpecificationsAntenna TestsThe following guidelines apply to the requirements described in Table 8-1 on page 43 and Table 8-2 on page 45:•Perform electrical measurements at room temperature (+20°C to +26°C) unless otherwise specified•For main and Rx diversity path antennas, make sure the antennas (including contact device, coaxial cable, connectors, and matching circuit with no more than six components, if required) have nominal impedances of 50  across supported frequency bands.a. These worst-case VSWR figures for the transmitter bands may not guarantee RSE levels to be within regulatory limits. The device alone meets all regulatory emissions limits when tested into a cabled (conducted) 50 ohm system. With antenna designs with up to 2.5:1 VSWR or worse, the radiated emissions could exceed limits. The antenna system may need to be tuned in order to meet the RSE limits as the complex match between the module and antenna can cause unwanted levels of emissions. Tuning may include antenna pattern changes, phase/delay adjustment, passive component matching. Examples of the application test limits would be included in FCC Part 22, Part 24 and Part 27, test case 4.2.2 for WCDMA (ETSI EN 301 908-1), where applicable.b.

Rev 3 Aug.17 47 4111025199: Design ChecklistThis chapter provides a summary of the design considerations mentioned throughout this guide. This includes items relating to the power interface, RF integration, thermal considerations, cabling issues, and so on.Note: This is NOT an exhaustive list of design considerations. It is expected that you will employ good design practices and engineering principles in your integration.Table 9-1: Hardware Integration Design ConsiderationsSuggestion Section where discussedComponent placementProtect the SIM socket so the SIM cannot be removed while the host is powered up. SIM Implementation on page 21If an ESD suppressor is not used, allow space on the SIM connector for series resistors in layout. (Up to 100  may be used depending on ESD testing requirements).SIM Implementation on page 21Minimize RF cable losses as these affect performance values listed in product specification documents. RF Connections on page 24AntennasMatch the module/antenna coax connections to 50 —mismatched antenna impedance and cable loss negatively affect RF performance. RF Connections on page 24If installing CDMA and UMTS modules in the same device, consider using separate antennas for maximum performance. Antenna and Cabling on page 25PowerMake sure the power supply can handle the maximum current specified for the module type. Power Consumption on page 30Limit the total impedance of VCC and GND connections to the SIM at the connector to less than 1  (including any trace impedance and lumped element components—inductors, filters, etc.). All other lines must have a trace impedance less than 2 .SIM Implementation on page 21Decouple the VCC line close to the SIM socket. The longer the trace length (impedance) from socket to module, the greater the capacitance requirement to meet compliance tests.SIM Implementation on page 21PCB signal routingUSB 2.0—Route these signals over 90  differential lines on the PCB.EMI/ESDInvestigate sources of localized interference early in the design cycle. Methods to Mitigate Decreased Rx Performance on page 27Provide ESD protection for the SIM connector at the exposed contact point (in particular, the CLK, VCC, IO, and RESET lines). SIM Implementation on page 21
Product Technical SpecificationRev 3 Aug.17 48 41110251Keep very low capacitance traces on the USIM_DATA and USIM_CLK signals. SIM Implementation on page 21To minimize noise leakage, establish a very good ground connection between the module and host. Ground Connection on page 25Route cables away from noise sources (for example, power supplies, LCD assemblies, etc.). Methods to Mitigate Decreased Rx Performance on page 27Shield high RF-emitting components of the host device (for example, main processor, parallel bus, etc.). Methods to Mitigate Decreased Rx Performance on page 27Use discrete filtering on low frequency lines to filter out unwanted high-order harmonic energy. Methods to Mitigate Decreased Rx Performance on page 27Use multi-layer PCBs to form shielding layers around high-speed clock traces. Methods to Mitigate Decreased Rx Performance on page 27ThermalTest to worst case operating conditions—temperature, voltage, and operation mode (transmitter on 100% duty cycle, maximum power).Thermal Considerations on page 37Use appropriate techniques to reduce module temperatures (for example, airflow, heat sinks, heat-relief tape, module placement, etc.). Thermal Considerations on page 37Host/Modem communicationMake sure the host USB driver supports remote wakeup, resume, and suspend operations, and serial port emulation.When no valid data is being sent, do not send SOF tokens from the host (causes unnecessary power consumption).Table 9-1: Hardware Integration Design Considerations (Continued)Suggestion Section where discussed
