Abstract:
A counter/divider where the counter/divider comprises a: a pre-scaler operable in a first mode to divide an input signal by M and in a second mode to divide the input signal by N, where N is greater than M; a first programmable counter, and a second programmable counter; and where the first and second programmable counters are responsive to an output of the pre-scaler and an output of the first counter controls whether the pre-scaler operates in the first mode or the second mode, wherein the first counter is operable to count to greater than one.
