SIM implemenution When designing the remote SIM interface, you must make sure that SIM signal integrity is not compromised. Some design recommendations include: - Total Impedance ot the VCC and GND connections to the SIM. measured at the module connector. should be less than 1 a to minimize voltage drop (includes any trace Impedance and lumped element components—inductors, tillers. etc). - Position the SIM connector 510 cm from the rnodute. Ila longer distance is required because at the host devtoe desrgn, use a shielded Wire assembty— connect one end as close as posstble to the SIM connector and the other end as close as possmle to the module connector. The shielded assenbly may help shield the SIM intertace lrorn system noise. - Reduce crosstalk on the US|M_DATA line to reduce the risk at tailures during GCF approval testing. 0 Avoid routing the USIM,CLK and USlMgDATA lines in parallel over distances >2 cm—cross—coupling ot these lines can cause tailures. - 36PP has stringent requirements tor IIO rise time (<1 us). signal level limits. and notse tn‘imuntty—cortSIder this carelully when developing your PCB layout. - Keep signal rise little <1 tie—keep USIM srg'tals as shor1 as possible. and keep very low capacitance traces on Ihe USIM_DATA and USIM‘CLK signals, Higt capacitance increases signal rise time, potentially causing your device to tail oertitication bets. . Add external pull-up resistors (15 kQ—ao kn). it required. between the USIMADATA and USIMJ’WR lines to optimize the signal rise time. - VCC line should be decoupled close to the SIM socket 0 SIM is specified to run up to 5 MHz (SIM clock ran). Take note 0! this speed in the placement and routlng ot the SIM signals and connectors. - You must decide whether eddticnal ESD protection is required tor your product. as it Is dependent on the application. mechanical enclosure. and SIM connector design. The SIM pins will require additional ESD protection it they are exposed to high ESD levels (LB. can be touched by a user). 0 Putting an optional decoupling capacitor at USIMJ’WH near the SIM socket is recommended—the longer the trace length (impedance) Irom the socket to the module, the greater the capacitance requirement to meet compliance tests. - Putting an optional series capacitor and resistor lamination (to ground) at USIM,CLK at the SIM socket to reduce EMI and increase signal integrity is recommended it the trace length between the SIM socket and module is long—47 pF and 50 a resistor are recommended. - Test your first prototype host hardware with a Comprion IT“ SIM test device at a suitable testing facility. 32 Proprietary and Confidential - Contents subject to change 2400074 Electrical Specifications Control interface (Signals) The LTET750 provides siglals tor: - Power control ol the module trom ll'ie host - LED driver output These slyials are surrmarized in Table 4-5 and paragraphs Ihat lollow.

Nate: Fa detailed electrical performance Elena. see Appendlx A: Anionne SpeaTiootibri on page 65 Choosing the correct antenna and cabling When matching antennas and cabling: - The antenna (and associated circuitry) should have a nominal Impedance ol 50 Q with a return loss 01 better than 10 dB across each lrequency band at operation. The system gain value altecls both radiated power and regulatory (FCC. IC, CE, etc.) test results. Designing custom antennas Consider the lollowmg potnts when designing custom antennas: ~ A skilled RF engineer should do the development to ensure that the RF perlormance Is maintained. . It both CDMA and UMTS rriodules WI" be installed in the same platlorm, you may want to develop separate antennas lor newmum pertormance. Determining the antenna's location When deeming where to put the antennas: o Antenna location may attect RF performance. Although the module Is shielded to prevent interference in most applications. the placement at the antenna is still very important—it the host deVice is insullicientty shielded. high levels at broadband or spurious noise can degrade the module's parlor- mat-ice. Connecting cables between the module and the antenna must have 50 Q impedance, It the impedance ol the module is mismatched. RF periormance is reduced s‘gnilicantlyi Antenna cables should be routed. it possuble. away lrom neise sources (swulching power supplles. LCD assemblies. etc). It the cables are near the neise sources. the noise may be coupled into the RF cable and into the antenna.

Ground connection When connecting the module to system ground: 0 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 at the module (shown in Figrre 51 on page 37). - Minimize ground noise leakage into the HF Depending on the host board design. noise could polenlially be coucled to the module lrom the host board. This Is mtnly an issue lor host designs that have Signals traveling along the length at the module, or circuitry operating at both ends oi the module interconnects. Interference and sensitivity Several interlerenoe sources can shoot the modules RF pertormanoe (RF desense). Common sources Include power supply noise and demo- generated HF. HF desense can be addressed through a combination cl mitigation techniques (Methods In mitigate decreased Fix periorrnance on page 40) and radated sensitile measurement (Radiated sensitivity measurement on page 41).

Customer Destgn Guidelines The severity at this intertorence depends on the closeness ol the other antennas to the module's antenna. To determine suttable locations tor each Wireless devtce‘s antenna. thoroughly evaluate your host device's design Host-generated RF interference All electronic computing devices generate RF lnterterence that can negatively sheet the receive sensitivtty ol the module. Proximity ol host electronics to the antenna in Wireless devices can contribute to decreased Rx pertormance. Components that are rnosl likely to cause this Include: - Microprocessor and memory . Display panel and display drivers 0 Switching-mode power supplies Device-generated RF interference The module can cause interterence With other devtces Wireless devtoes such as AirPrirne embedded modules transmit in bursts (pulse transients) tor seldurations (RF burst trequencies). Hearing aids and speakers convert these burst lrequencies into audible trequencies, resulting in audible noise. Methods to mitigate decreased Rx performance It Is Important to Investigate sources ol locallzed Interference early In the desrgn cycles To reduce the eftect ol device—generated RF on th perlormance: - Put the antenna as tar as posSible lrom sources ot Interference. The drawback Is that the module may be less convenient to use. - Shield the host devtcei The module tlsell Is well shielded to avord external tnterterenoe. However. the antenna cannot be shielded tor obvtous reasons In most Instances It is necessary to employ shielding on the components at the host devrce (such as the main processor and parallel bus) that have the highest RF emi ssions, 0 Filter out unwanted high~order harmonic energy by using discrete ltltenng on low lrequency lines. . Form shielding layers around high-speed clock traces by using mitt-layer PCBS, - Route antenna cables away lrorri notse sources, Radiated Spurious Emissions (RSE) When desrgmng an antenna tor use with Aerrime embedded modules. the host device with an AirPrime embedded module must satiety the radiated spurious emissron (RSE) test cases described in: - (CDMA) Pieter to COM standards for receive-only mode, and local regulatory bodies tor transmit mode (transmitter is operating), 40 Prophetary and Confidential - Cements subject to change 2400074 RF Specifications Note lhal antenna Impedance attects radiated emissmns. which must be compared against the conducted 50-ohrn emissions baseline (AIrPrtme embedded modules meet the 500nm conducted emissions requirement) Radiated sensitivity measurement A Wireless host demos contains many noise sources that contribute to a reduction in Fix periormance.
