Semtech adds to Tri-Edge portfolio

The GN2555 is a quad channel PAM4 CDR with integrated directly modulated laser (DML) drivers.

The GN2556 is a quad channel PAM4 CDR with integrated externally modulated laser (EML) drivers.

The GN2555 and GN2556 are fully compliant to IEEE 802.3bs and Open Eye MSA specifications.

“The GN2555 DML drivers and the GN2556 EML drivers offer proprietary laser compensation to enable a wide range of low cost laser options for data centre interconnects”, says Semtech’s Weiliang Deng.

The GN2555 and GN2556 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.

Semtech’s Tri-Edge CDR portfolio for data centers includes:

·         GN2558: PAM4 4x56G CDR + VCSEL Driver

·         GN2559: PAM4 4x56G CDR + TIA

·         GN2538: PAM4 2x56G CDR + VCSEL Driver

·         GN2539: PAM4 2x56G CDR + TIA

·         GN2559S: New Low Power Quad PAM4 CDR Receiver With Integrated TIA
