Next generation Tri-Edge™ CDR receiver offers ultra-low power, reduced latency and low cost for short reach and long reach optical links
Semtech Corporation a leading global supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, announced sampling of the GN2559S, Semtech’s new ultra-low power Tri-Edge™ clock and data recovery (CDR) receiver solution to enable next-generation data center short reach (SR) and long reach (LR) optical links. The GN2559S is a next generation Tri-Edge PAM4 receiver with quad PAM4 CDRs and integrated linear transimpedance amplifiers (TIAs). In addition to its small size, it offers low latency due to the Tri-Edge signal integrity platform, and a 400mW power reduction from the previous generation receiver.
