Abstract

A demodulator for pulse-width modulated clock signals is disclosed. In one aspect, the demodulator includes an edge detector configured to detect transitions in a reference clock and output a signal indicative of timing of the detected transitions. The demodulator may also include a modulation detection circuit configured to identify modulation events of at least one pulse-width modulated pulse in the reference clock based on the signal output from the edge detector and output a signal indicative of the at least one pulse-width modulated pulse modulation event being identified. The demodulator may further include a retiming circuit configured to generate an output clock synchronized with the at least one pulse-width modulated pulse modulation event based on the signal output from the modulation detection circuit.
