Semtech releases CDR receiver for data centre optical links

1 min read

Semtech has announced initial production availability of GN2559S, the company’s new low power Tri-Edge CDR receiver solution to enable next-generation data centre short-reach (SR) and long-reach (LR) optical links.

The Tri-Edge GN2559S is a next generation Tri-Edge PAM4 receiver with quad PAM4 CDRs and integrated linear transimpedance amplifiers (TIAs) offering a combination of ultra-low power and low latency receiver performance that meets the needs of high-performance computing (HPC), artificial intelligence (AI) and Cloud data centre networks.

“The initial production availability of the next generation Tri-Edge GN2559S receiver is moving the needle for the strong and fast growing PAM4 data centre market. Building upon the Tri-Edge PAM4 SR CDR chipset, which was successfully developed for major Cloud data centres, the GN2559S will offer more power saving and enhanced receiver performance,” explained Tim Vang, vice president, marketing and applications for Semtech’s Signal Integrity Products Group. “With 400mW power reduction from the previous generation receiver, the GN2559S enables industry best in class power consumption for both SR and LR data centre optical interconnects.”

The Tri-Edge GN2559S is now in initial production and Semtech will also offer a complete Reference Design Kit (RDK) for SR and LR applications to enable rapid adoption of Semtech’s solution.

Semtech’s Tri-Edge CDR portfolio includes:

  • GN2559S: PAM4 4x56G CDR + TIA
  • GN2558: PAM4 4x56G CDR + VCSEL Driver
  • GN2559: PAM4 4x56G CDR + TIA
