GTM353W Integration Manual 3.3 UICC interface guidelines 3.3.1 Introduction This section describes how to design the UICC (USIM)-card interface for connection with the GTM. The baseband processor has an integrated UICC interface compatible with the ISO7816 IC card standard. This is wired to the PCIExpress Mini Card connector (PCIE connector) in order to be connected to an external UICC card holder (see Figure 5: (U)SIM pin assignment).

GTM353W Integration Manual 3.3.3.1 Contact activation and deactivation The Terminal shall connect, activate and deactivate the UICC in accordance with the Operating Procedures specified in ISO/IEC 7816-3 [12]. For any voltage level, monitored during the activation sequence, or during the deactivation sequence following normal power-down, the order of the contact activation/deactivation shall be respected.

GTM353W Integration Manual 3.3.4 Electrical interface The (U)SIM card holder is connected with the module by means of long wires. The (U)SIM card holder and wires are radiated on with different types of noisy signals, e.g. the radiation signals of the module antenna. The SIM interface signals conduct this noise into the module and radiate these signals into the module, with potential disasterous results.
GTM353W Integration Manual 3.3.4.2 Maximum Trace Length The maximum trace length depends on the trace capacitance, but on average it is advisable to limit the length to a maximum of 200mm. The module controls the signals RST and CLK. A totem-pole output drives these signals high or low. The signal I/O is a bi-directional data line. The I/O interface is shown in Figure 10. The module and the (U)SIM (in the SIM card holder), located on both ends of the lines, control this data line.

This result in a maximum capacitive load of 70pF on the I/O line.
GTM353W Integration Manual 3.3.5 Practical implementation The (U)SIM signals on the GTM are connected to the PCI Express MiniCard edge connector. The method of routing the signals to the SIM card holder depends on which connecter is used. Note that only one of the two connectors can be used at once, the other needs to be left floating. 3.3.5.1 PCI Express MiniCard edge connector Signal Routing When using this connector the SIM signals are routed throughout the PCB.
GTM353W Integration Manual 3.3.5.2 FH19 Signal Routing The connection between the GTM and UICC cardholder is made by an FFC (flexible flat cable). Shielding in this environment is much more problematic. In many cases the signals are not shielded at all. However, the ground wires between every active signal grants certain immunity against noise. However an additional PCB board should be designed to host cardholder and some decoupling capacitors..
