ALL-DIGITAL CLOCK DATA RECOVERY DEVICE AND A TRANSCEIVER IMPLEMENTED THEREOF, CAPABLE OF PREVENTING JITTER DUE TO A QUANTIZATION ERROR

摘要

PURPOSE: All-digital clock data recovery device and a transceiver implemented thereof are provided to digitalize the whole of a clock data restoring unit by implementing a charge pump circuit and a voltage controlled generator with a digital circuit.;CONSTITUTION: A phase detector(10) samples serial data. A phase detector outputs the digital signal sequence of data and edge. A deserializer changes the digital signal sequence into a bus signal. A digital controlled oscillator(200) is comprised of a multi-stage inverter chain. The digital controlled oscillator comprises a variable resistance switching matrix the digital controlled oscillator generates a clock having an adjusted oscillation frequency. The digital controlled oscillator provides a clock to the phase detector.;COPYRIGHT KIPO 2010
