A burst-mode clock-and-data-recovery (CDR) system for a multi-channel vertical-cavity surface-emitting laser (VCSEL)-based non-return-to-zero (NRZ) optical link’s quarter-rate receivers is presented. that utilizes proxy timing recovery for fast turn-on time. The proxy timing recovery scheme takes advantage of correlated data jitter over parallel optical lanes typically deployed... https://www.jmannino.com/amazing-price-Colts-Pets-First-Nylon-Dog-Collar-mega-value/
