Semtech Announces Production Availability of Best-in-Class FiberEdge® Linear Transimpedance Amplifier and Laser Driver for Short Reach 400G and 800G Data Center Applications

Production of highly linear short reach amplifier and laser driver enables high performance and low-cost optical transceivers for multi-mode fiber applications

CAMARILLO, Calif.–(BUSINESS WIRE)–Semtech Corporation (Nasdaq: SMTC), a high-performance semiconductor, IoT systems and cloud connectivity service provider, today announced production availability of the FiberEdge® GN1816 and GN1848 chipset to its portfolio of PAM4 Transimpedance Amplifiers (TIAs) and Linear Laser Drivers.

The production availability of the FiberEdge GN1816 and GN1848 chipset marks the formal extension of Semtech’s FiberEdge portfolio into the 100G per lane multi-mode fiber market,” said Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “The high linearity and low noise of both the GN1816 and GN1848 provide the necessary features needed in high-speed short reach interconnects, enabling re-timed, linear drive and active optical cable (AOC) applications.”

The FiberEdge GN1816 is a 56GBd feature-rich quad 250μm-pitch low power, low cost, low noise and high gain TIA. The FiberEdge GN1848 is a 56GBd quad low power, low cost, highly linear and industry leading Vertical-Cavity Surface-Emitting Laser (VCSEL) driver. Both chips are available as wire-bondable bare dies and are designed for 400GBASE-SR4/VR4 and 800GBASE-SR8/VR8 PAM4 multi-mode optical transceivers and AOCs.

Multiple customers have already experienced exceptional performance using the FiberEdge GN1816 and GN1848 in Digital Signal Processing (DSP) based solutions, first generation of Linear Pluggable Optics (LPO) and AOCs. To see a live demonstration of the GN1816 and GN1848 chipset in action in an 800G SR8 re-timed module, visit Semtech’s booth #11D51 at the 24th China International Optoelectronic Exposition (CIOE) in Shenzhen from September 6 to 8, 2023.
