Semtech unveils FiberEdge 56GB EML driver for data center applications to boost module manufacturing yield, drive down costs

Semtech Corp. has announced immediate availability of its FiberEdge linear electro-absorption modulated lasers (EML) driver. The new driver is ideal for PAM4-based Ethernet optical modules, including 100G-FR, 400G-DR4 and 400G-FR4.

The FiberEdge linear EML driver (GN1862) is a bare die single-ended driver specifically designed to provide the performance to power ratio required by hyperscale data center operators. The driver delivers two volts of single-ended swing while minimizing total harmonic distortion (THD) and group delay (GD) to increase module manufacturing yield, thereby driving down costs. 

As a bare die device, the new FiberEdge solution is ideal for both single channel (100G) and quad channel (400G) PAM4 applications.

Semtech’s optical networking product platforms provide high-performance signal integrity for optical module solutions used by companies in the data center/enterprise networking, wireless infrastructure and passive optical network/Fiber to the markets.

Semtech offers comprehensive portfolios of optical transceiver IC products ranging from 100Mbps to over 100Gbps, supporting key industry standards such as Fibre Channel, InfiniBand, Ethernet, Common Public Radio Interface (CPRI), Passive Optical Network (PON), Synchronous Optical Networking (SONET), and PCI Express. Semtech is also investing in key technologies to enable communication systems at 400Gbps and beyond. 

“Over the past months, data center architects have discovered that the key to successful 100G per lambda deployments is performance,” said Dr. Timothy Vang, vice president of marketing and applications for Semtech’s Signal Integrity Products Group. “The GN1862 EML driver delivers enough margin to specifications to enable modules with up to 40km reach.”
