2: Power Interface 2 Overview of operation Note: This chapter contains information for both the CDMA (MC5720) and GSM (MC8755/8765) modules. Information that is unique to one module type is clearly identified. The module is designed to use a 3.3V (nominal) power supply, provided by the host. It is the host’s responsibility to provide safe and continuous power to the module at all times; the module does NOT have an independent power supply, or protection circuits to guard against electrical issues. The module’s power state is controlled by the host’s assertion/ de‐assertion of the W_Disable# signal. The module also monitors its supply voltage and requests shutdown if the supply is insufficient. Power signals The module must be connected to a 3.3V power supply (as indicated in PCI Express Mini Card Electromechanical Specifi‐cation Revision 1.1). The MC8755/8765 has more power pins than the MC5720 due to higher peak current requirements for GSM devices. For detailed pinout and voltage / current requirements of these modules, refer to MC5720 MiniCard Product Specification (Document 2130599) and MC8755/MC8765 PCI Express MiniCard Product Specification (Document 2130637). Electrostatic discharge (ESD) You are responsible for ensuring that the host has adequate ESD protection on digital circuits and antenna ports: • (Operational) RF port (antenna launch and RF connector): IEC‐61000‐4‐2 — Level (Electrostatic Discharge Immunity Test) • (Non‐operational) Host connector interface: JESD22‐A114‐B+/‐1kV Human Body Model and JESD22‐C101 +/‐125 V Charged Device Model Specific recommendations are provided where needed in this guide, however, the level of protection required depends on your application. Rev 0.92 Nov.05 9

MC5720/8755/8765 Hardware Integration Guide Note: The module unit defaults to the Normal state when VCC3.3 is first applied in the absence of W_Disable# control. Note: The difference between the Disconnected and Off states is that in the Off state, the module is still connected to the power source and draws minimal current. Note: ESD protection is highly recommended for the SIM connector at the point where the contacts are exposed, and any other signals from the host interface that would be subjected to ESD by the user of the end product. Module power states At any time, the module will be in one of four power states: • Disconnected No power to the module. • Off Power to the module, but the module is powered off. • Normal The module is active. Several modes are possible (Receive, Transmit, Sleep, Shutdown). • Low power (“airplane mode”) The module is active, but RF is disabled. State machines are implemented in the module to monitor the power supply and operating temperature. Disconnected state This state occurs when there is no power to the module — the host power source is disconnected from the module and all voltages associated with the module are at 0V. Whether the host device is also powered off depends on the power rail design. If the connection between the power rail and the module is controlled by the host, the host can stay powered on and cut the power to put the modem into the disconnected state. If the power rail is shared between the host device and the module, the host is powered off when the module is powered off. Off state In this state, the host is powered up and the module is powered down (but still connected to the power source). The host keeps the module powered off by asserting (driving low) the W_Disable# signal. In this state, the module draws minimal current. 10 2130114

Power Interface Rev 0.92 Nov.05 11 Normal state Note: This is the default state when VCC3.3 is first applied in the absence of W_Disable# control. This is the active state of the module. While in this state: • The module is fully powered. • The module is capable of placing/receiving calls or estab‐lishing data connections on the wireless network. • The USB interface is fully active. Low power mode In this power state, RF (both Rx and Tx) is disabled in the module, but the USB interface is still active. This low power mode (ʺairplane modeʺ) is controlled by a software command through the host interface. For instructions on using appropriate commands, refer to AT Command Set for User Equipment (UE) (Release 6) (+CFUN=0 command), EM5625/MC5720 CnS Reference (Document 2130643) (CNS_RADIO_POWER [0x1075]), or MC87xx Modem CnS Reference (Document 2130602) (Disable Modem). Usage models Usage models can be used to calculate expected current consumption. A sample usage model is provided in Table 2‐1. This example model applies to a battery‐operated device. In practice, because the module will be isolated from the battery (the host device manages the power source), the mAh ratings will depend on the device’s supply efficiency.

MC5720/8755/8765 Hardware Integration Guide The module automatically enters slotted sleep mode when there is no transmission or reception occurring (SCI = 2). Transmit power is assumed to be +3 dBm . 12 2130114

3: RF Integration 3 Note: To disconnect the antenna, make sure you use the Hirose U.FL connector removal tool (P/N UFL-LP-N-2(01) to prevent damage to the module or coaxial cable assembly. RF connection Consider the following when attaching an antenna to the module: • Use a Hirose U.FL connector (model U.FL #CL331‐0471‐0‐10) to attach an antenna to a connection point on the module, as shown in Figure 3‐1 (The main RF connector on the top side; the diversity RF connector on the bottom side). • Match coaxial connections between the module and the antenna to 50 Ω. • Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna cabling is 0.5 dB. Figure 3-1: Antenna connection points and mounting holes Ground connection When 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 (as shown in Figure 3‐1). • Minimize ground noise leakage into the RF. Depending on the host board design, noise could potentially be coupled to the 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. Rev 0.92 Nov.05 13

MC5720/8755/8765 Hardware Integration Guide Shielding The module is fully shielded to protect against EMI and to ensure compliance with FCC Part 15‐ “Radio Frequency Devices” (or equivalent regulations in other jurisdictions). Note: The module shields must NOT be removed. Antenna and cabling When selecting the antenna and cable, it is critical to RF perfor‐mance to match antenna gain and cable loss. Choosing the correct antenna and cabling Consider the following points for proper matching of antennas and cabling: • The antenna (and associated circuitry) should have a nominal impedance of 50 Ω with a return loss ≤ 10 dB across each frequency band of operation. • The system gain value affects both radiated power and regulatory (FCC, IC, CE, etc.) test results. Developing custom antennas Consider the following points when developing custom‐designed antennas: • A skilled RF engineer should do the development to ensure that the RF performance is maintained. • Identify the bands that need to be supported, particularly when both the MC5720 and MC8755/8765 will be installed in the same platform. In this case, you may want to develop separate antennas for maximum performance. Determining the antenna’s location Consider the following points when deciding where to put the antenna: • Antenna location may affect RF performance. Although the module is shielded to prevent interference in most applica‐tions, the placement of the antenna is still very important‐if the host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the module’s performance. • Connecting cables between the module and the antenna must have 50 Ω 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, 14 2130114

Note: These modules are based on ZIF (Zero Intermediate Frequency) technologies; when performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate Frequency) components from the module to consider. RF Integration etc.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna. Disabling the diversity antenna (MC5720) If your host device is not designed to use the MC5720’s diversity antenna, terminate the interface with a no‐connect. Interference and sensitivity Several sources of interference can affect the RF performance of the module (RF desense). Common sources include power supply noise and device‐generated RF. RF desense can be addressed through a combination of mitigation techniques and radiated sensitivity measurement. Power supply noise Noise in the power supply can lead to noise in the RF signal. The power supply ripple limit for the module is no more than 200 mVp‐p1Hz to 100 kHz. This limit includes voltage ripple due to transmitter burst activity Interference from other wireless devices Different wireless devices operating inside the host device can cause interference that affects the module. To determine the most suitable locations for each antenna 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. Rev 0.92 Nov.05 15

MC5720/8755/8765 Hardware Integration Guide Note: The module can cause interference with other devices such as hearing aids and on-board speakers. Wireless devices such as the MiniCard 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. Device-generated RF All electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module (RF desense). The proximity of host electronics to the antenna in wireless devices can contribute to RF desense. Components that are most likely to cause RF desense include: • Microprocessor and memory • Display panel and display drivers • Switching‐mode power supplies These, and other high‐speed devices (in particular, the processor) can cause RF desense because they run at frequencies of tens of MHz. The rapid rise and fall of these clock signals generates higher‐order harmonics that often fall within the operating frequency band of the module, causing RF desense. Example On a sub‐system running at 40 MHz, the 22nd harmonic falls at 880 MHz, which is within the cellular receive frequency band. Note: In practice, there are usually numerous interfering frequencies and harmonics. The net effect can be a series of desensitized receive channels. 16 2130114
