Figure 5: UICC/SIM/USIM interface
The total cable length between the SMT application interface pads on PXS8 and the pads of
the external SIM card holder must not exceed 100mm in order to meet the specifications of
3GPP TS 51.010-1 and to satisfy the requirements of EMC compliance.
To avoid possible cross-talk from the CCCLK signal to the CCIO signal be careful that both
lines are not placed closely next to each other. A useful approach is using the GND line to
shield the CCIO line from the CCCLK line.
