It is expected that you will employ good design practices and engineering principles in your integration.Table 7-1: Hardware integration design considerations Suggestion Section where discussedComponent placementProtect the USIM socket so that the USIM cannot be removed while the host is powered up.USIM operation page 67If an ESD suppressor is not used, allow space on the USIM connector for series resistors in layout (up to 100 Ω may be used depending on ESD testing requirements).USIM operation page 67Minimize RF cable losses as these affect the performance values listed in the product specification document.RF connection page 39AntennasMatch the module / antenna coax connections to 50 Ω — mismatched antenna impedance and cable loss negatively affects RF performance.RF connection page 39If installing both the MC57xx and MC87xx in the same device, consider using separate antennas for maximum performance.Antenna and cabling page 40PowerLimit host power rail dips caused by module inrush current by adding sufficient capacitance to the host power rail.Inrush currents page 24Make sure the power supply can handle the maximum current specified for the module type.Current consumption overview page 27Limit the total impedance of VCC and GND connections to the USIM at the connector to less than 1 Ω (including any trace impedance and lumped element components — inductors, filters, etc.). All other lines must have a trace impedance less than 2 Ω.USIM operation page 67

The longer the trace length (impedance) from socket to module, the greater the capacitance requirement to meet compliance tests.USIM operation page 67EMI / ESDInvestigate sources of localized interference early in the design cycle.Methods to mitigate decreased Rx performance page 42Provide ESD protection for the USIM connector at the exposed contact point (in particular, the CLK, VCC, IO, and RESET lines).USIM operation page 67Keep very low capacitance traces on the XIM_DATA and XIM_CLK signals.To minimize noise leakage, establish a very good ground connection between the module and host.Ground connection page 39Route cables away from noise sources (for example, power supplies, LCD assemblies, etc.).Methods to mitigate decreased Rx performance page 42Shield high RF-emitting components of the host device (for example, main processor, parallel bus, etc.).Methods to mitigate decreased Rx performance page 42Use discrete filtering on low frequency lines to filter out unwanted high-order harmonic energy.Methods to mitigate decreased Rx performance page 42Use multi-layer PCBs to form shielding layers around high-speed clock traces.Methods to mitigate decreased Rx performance page 42ThermalTest to worst case operating conditions — temperature, voltage, and operation mode (transmitter on 100% duty cycle, maximum power).Thermal considerations page 73Use appropriate techniques to reduce module temperatures. (airflow, heat sinks, heat-relief tape, module placement, etc.)Thermal considerations page 73Host / Modem communicationMake sure the host USB driver supports remote wakeup, resume, and suspend operations, and serial port emulation.USB handshaking page 62When no valid data is being sent, do not send SOF tokens from the host (causes unnecessary power consumption).USB handshaking page 62Table 7-1: Hardware integration design considerations (Continued)Suggestion Section where discussed

Antenna Peak Gain is not a good indication of antenna performance when integrated with a host device; the antenna does NOT provide omni-directional gain patterns. Peak Gain performance can be affected by parameters such as antenna size, location, design type, etc. The antenna gain patterns remain fixed unless one or more of these parameters changes.Table A-8: Peak and average antenna gainAntenna Peak gainaa.
