Figure 5: UICC/SIM/USIM interface
The total cable length between the SMT application interface pads on PHS8-US 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.
