Abstract

See full text

A circuit includes a time delta detector configured to receive an input clock signal and a reference clock signal and generate a delta pulse signal and a reference pulse signal. A comparison circuit is configured to receive the delta pulse signal and the reference pulse signal. The comparison circuit generates an output indicative of a bit of a time difference between the input clock signal and the reference clock signal. A control circuit is configured to receive the output from the comparison circuit. The control circuit maintains a count of the time difference between the input clock signal and the reference clock signal.
