Input Impedance of SC block in PSoC1

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

     

    Answer:

    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)

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