CDR CIRCUIT, RECEIVER, AND TRANSMITTING-RECEIVING SYSTEM

摘要

A CDR circuit, a receiver, and a transmitting-receiving system weight the output of the nonlinear phase detector that receives received data and the recovery clock on the basis of whether a clock out-of-phase with the recovery clock lags or leads in phase with respect to the received data, and adjust the phase of the recovery clock on the basis of the weighted output.
