ABSTRACT:
A timing signal generator produces a timing signal having one or more pulses of adjustable phase relative to pulses of a stable reference clock. The timing signal generator employs a low jitter retriggerable oscillator to produce a set of tap signals. The tap signals are frequency locked to the reference clock signal but are evenly distributed in phase. The timing signal generator times the pulses of its output timing signal using pulses of the various tap signals as timing references. Each cycle of the oscillator is triggered by a pulse of the reference clock signal to minimize timing signal jitter. Phase lock loops frequency lock the tap signals to the reference clock and ensure predictability of the timing signal pulse timing relative to the reference clock signal.
