Semtech Releases Quad 25Gbps Chipset for 100G SR4

Semtech released a new chipset for quad channel 100G-SR4 optical interconnects operating at 25.78 Gbps.

The GN2108 is a quad channel CDR with integrated vertical cavity surface emitting laser (VCSEL) drivers, and the GN2109 is a quad channel CDR with integrated transimpedance amplifiers (TIAs). A full suite of on-chip features minimizes external components and helps customers speed up their hardware and firmware development.

Semtech said its GN2108 VCSEL driver was architected to compensate for optical distortion introduced by VCSELs, enabling extended reach well beyond the SR4 standard to greater than 300m over OM4 fiber, operation with lower bandwidth and lower cost VCSELs, as well as operation with lower VCSEL bias settings for lower power and higher VCSEL reliability.

“The GN2108 and GN2109 chipset has strong traction with our customers,” said Dr. Timothy Vang, Senior Director of Datacom Marketing for Semtech’s Signal Integrity Product Group. “The performance and feature set of the GN2108 and GN2109 is enabling our customers to quickly bring to market winning solutions for 100Gbps QSFP28 and Active Optical Cables (AOCs) for datacenters and a wide range of other applications.”
