Semtech Demonstrates New 53GBaud PAM4 Linear Driver and Transimpedance Amplifier at OFC 2017

High-performance IC platform supports next-generation 100G optical networking modules

LOS ANGELES – Optical Fiber Conference and Exhibition (OFC), March 20, 2017 (GLOBE NEWSWIRE) -- Semtech Corporation (Nasdaq:SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced a new 53GBaud PAM4 linear driver and transimpedance amplifier for 100G and 400G optical networking modules at OFC 2017. Semtech will privately demonstrate the new chipset in its OFC booth (#2575) at the Los Angeles Convention Center March 21-23.

The new 53GBaud PAM4 linear driver and transimpedance amplifier chipset supports the rapid adoption of 100G optical networking modules by hyperscale and cloud data center customers that are upgrading capacity and throughput. These high-bandwidth linear products reduce required optical components compared to NRZ or 26GBaud PAM4-based solutions, enabling lower cost modules and a streamlined roadmap to 400G (4x100G) optical networking applications.

“53GBaud PAM4 technology provides the optimal path to both 100G and 400G by creating a cost-efficient, integrated solution for customers,” said Imran Sherazi of Marketing and Applications for Semtech’s Signal Integrity Products Group. “The integrated solution provides a seamless interface to PAM4 optics and is tailored to next-generation 100G modules expected to pave the way to 400G.”

The GN1189 is a high-bandwidth 53GBaud linear modulator driver, and the GN1089 is a high-performance, low-noise linear 53GBaud transimpedance amplifier. The OFC demonstration also includes a Receiver Optical Sub-Assembly (ROSA).
