Zusammenfassung:A receiver is provided that includes a time-to-digital converter for converting a phase difference between a clock signal and a received data signal into a phase-difference digital code. The receiver also includes a logic circuit that controls a programmable delay line to delay the clock signal into a delayed clock signal by a delay that is responsive to a difference between the phase-difference code and a unit interval for the clock signal. The delayed clock signal clocks a flip-flop to register the received data signal.
