 The length of cable from the module to the (U)SIM card connector shall not exceed 100mm. Longer cable reduces signal quality.  USIM_CLK and USIM_DATA signals are ground isolated to avoid mutual interference. If it is difficult to do so, (U)SIM signal needs to be ground protected as a set;  The filter capacitor and ESD device of (U)SIM card signal cable should place close to the (U)SIM card connector.  Please select equivalent capacitor is 22pF~33pF for ESD device.
