Semtech Corporation announced new integrated circuits (IC), the Tri-Edge GN2555 and GN2556. The latest ICs are a part of Semtech’s Tri-Edge clock and data recovery (CDR) transmitter solutions to enable next-generation data center long reach (LR) optical links. The GN2555 is a quad-channel PAM4 CDR with integrated directly modulated laser (DML) drivers and the GN2556 is a quad-channel PAM4 CDR with integrated externally modulated laser (EML) drivers. The GN2555 and GN2556 are fully compliant with IEEE 802.3bs and Open Eye MSA specifications.

The Tri-Edge GN2555 and GN2556 are now available for sampling and can be paired with the Tri-Edge GN2559S receiver for a complete 200G FR4/LR4 solution. Semtech offers complete reference design kits (RDK) for the solutions to enable rapid adoption.
