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

Chip delivers industry-leading low power, low noise, high gain, and wide overload performance

CAMARILLO, Calif., March 8, 2022 – Semtech Corporation (Nasdaq: SMTC), a leading global supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced the production availability of GN1812, a new addition to the FiberEdge® portfolio of PAM4 transimpedance amplifiers (TIAs), to enable next-generation data center single-mode connectivity.

“The production availability of GN1812 builds on Semtech’s continuous investment in technology for the advancement of the FiberEdge physical medium dependent (PMD) platform. The FiberEdge GN1812 is ideally suited to a wide variety of PAM4 optics both in the Chip on Board (COB) and in the silicon photonics (SiPh) space,” said Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “Semtech expects to continue to play a leading role in enabling the deployment of next generation 100G per lane optical transceivers with our industry-leading FiberEdge PAM4 TIA portfolio.”

The FiberEdge GN1812 is a quad 750μm-pitch low power, low noise, high gain, high bandwidth TIA that delivers wide overload performance and low group delay variation, making it ideal for 400GBASE-DR4, FR4 and LR4 PAM4 optical transceivers and COB optical assemblies. The GN1812 is available as wire-bondable bare die and is part of the complete Semtech FiberEdge TIA portfolio that supports 400G and 800G data center applications.

Semtech’s FiberEdge TIA portfolio includes:

• GN1089: Single Channel 56GBd PAM4 Linear TIA
• GN1089SC2: Single Channel 28GBd PAM4 Linear TIA
• GN1800: Second Generation Single Channel 56GBd PAM4 Linear TIA
• GN1800SC2: Second Generation Single Channel 28GBd PAM4 Linear TIA
• GN1700: 50Gbps PAM Linear TIA for 5G Wireless
• GN1810: Quad 56GBd PAM4 Linear TIA
• GN1812: Second Generation Quad 56GBd PAM4 Linear TIA
• GN1814: 500μm pitch Quad 56GBd PAM4 Linear TIA
