Abstract
A circuit includes a phase detector circuit and a data detection circuit. The phase detector circuit generates first and second phase detection signals based on a data signal and a periodic signal. The data detection circuit includes logic circuitry that generates a logic signal based on the first and second phase detection signals. The data detection circuit also includes a plurality of delay elements that generate a series of delayed detection signals based on the logic signal. The data detection circuit generates a data detection signal indicating when the data signal contains data based on the series of delayed detection signals.
