Counts read by register at 500 Hz = x1

Counts read by proceessor at 500.01 Hz = x2
500.01Hz
Fs Fs
The difference is 50 counts, then x1 x2 50
500 Hz 500.01Hz
Or the sample clock frequency: Fs 1250025000Hz 1.25GHz
In this case, the clock frequency must be 1.25GHz in order to achieve 50
count differences for a resolution of 0.0001 MHz at the input frequency of 5
MHz.
