Abstract

Generation of clock waveforms which have a frequency, phase offset, and duty cycle that is relative to a periodic reference signal. The outputs of a voltage controlled ring oscillator are directly applied to drive the inputs of a programmable AND, fixed OR array (PAL) to produce pulses of varied and phase offset and duty cycle. The phase offset has a resolution of one nanosecond. Additionally, the pulses generated can be ORed together within the to produce clock waveforms that are multiples of the input frequency.
