Figure 4: External UICC/SIM/USIM card holder circuit
The total cable length between the SMT application interface pads on PDS5-E/PDS5-US and
the pads of the external SIM card holder must not exceed 100mm in order to meet the specifi-
cations 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 a GND line to shield
the CCIO line from the CCCLK line.
