“The initial production availability of the next generation Tri-Edge GN2559S receiver is moving the needle for the strong and fast growing PAM4 data center market. Building upon the Tri-Edge PAM4 SR CDR chipset, which was successfully developed for major Cloud data centers, the GN2559S will offer more power saving and enhanced receiver performance,” said 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 center 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.
