Patent abstract
An embodiment of the present invention provides a system for detecting a phase-shifted signal at high frequencies in data and clock recovery circuitry. An up-pulse generator, in one embodiment, provides output pulses having a duration exceeding the duration of input pulses upon detection of a phase-shifted signal leading the reference signal. A down-pulse generator provides output pulses having a duration exceeding the duration of input pulses upon detection of a phase-shifted signal lagging the reference signal.
