Semtech Announces Production of New Tri-Edge, a PAM4 CDR Platform for Data Center Applications

The chipset enables lower power, reduced latency and low cost for up to 100 meter multi-mode fiber links.

Semtech, a supplier of analog and mixed-signal semiconductors and advanced algorithms, announced production availability of GN2558 and GN2559, Semtech's Tri-Edge CDR SR solutions to enable next-generation data center multi-mode interconnectivity. GN2558 is a quad PAM4 CDR with an integrated VCSEL driver, and GN2559 is a quad PAM4 CDR with an integrated linear transimpedance amplifier (TIA).

The GN2558 CDR includes proprietary VCSEL compensation to enable a wide range of VCSEL options with fully adaptive input equalization and ideal startup to streamline system bring up. The GN2559 linear TIA and CDR provides ideal receiver performance with suitable adaptation and startup. The GN2559 includes configurable output equalization enabling robust electrical interfaces.
