Input Impedance of SC block in PSoC1

Version 1
    Question: What is the input impedance of SC clock in PSoc1?



    Input impedance of SC block depends on the functionality and the value of input capacitor used. It can be calculated from formula:

    Input Impedance = 1/(Fs * C)

    Fs is the switching frequency (column clock/4) and
    C is value of input capacitor
