The maximum rise-time of I/O equals 1µs. This result in a maximum capacitive load of 70pF

on the I/O line. The maximum capacitance is the sum of all capacitors:

• Suppression capacitor on GTM, typical 17pF

• SIM driver logic on GTM, typical 5pF

• Suppression capacitor on SIM card holder, 10pF.

• Test equipment, maximum 30pF load.

• Connectors

The sum of al these capacitors, without the trace capacitance, equals 62pF. The trace

capacitance is 70pF minus all other capacitance. The maximum trace capacitance equals 70 –

62 = 8pF. This capacitance typically gives lead to a maximum length of 200mm in the worst

case.
