Clock and data recovery using LC voltage controlled oscillator and delay locked loop
Abstract:
A clock and data recovery (CDR) circuit includes an inductor-capacitor voltage controlled oscillator (LCVCO) configured to generate a clock signal with a clock frequency. A delay locked loop (DLL) is configured to receive the clock signal from the LCVCO and generate multiple clock phases. A charge pump is configured to control the LCVCO. A phase detector is configured to receive a data input and the multiple clock phases from the DLL, and to control the first charge pump in order to align a data edge of the data input and the multiple clock phases.
