Semtech Announces 25G Burst Mode Transimpedance Amplifier for Next Generation Multi-Gigabit PON

Semtech Announces Availability of Reduced Channel Pitch FiberEdge® Linear Transimpedance Amplifier for 400G and 800G Data Center Applications

Feature-rich chip delivers exceptional performance with 500μm pitch for QSFP-DD, OSFP and Chip on Board applications

CAMARILLO, Calif., March 8, 2022Semtech Corporation (Nasdaq: SMTC), a leading global supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced the immediate sampling availability of GN1814, a new addition to the FiberEdge® portfolio of PAM4 transimpedance amplifiers (TIAs), to enable next-generation data center single-mode connectivity.

“As higher density optical transceivers start to deploy in the data center market, Semtech has addressed the requirement to reduce optical chip footprint by developing quad TIAs at lower channel pitch,” said Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “The availability of FiberEdge GN1814 represents a major step forward for the deployment of next generation 100G/lane high density optical transceivers such as QSFP-DD and OSFP.”

The FiberEdge GN1814 is a feature-rich quad 500μm-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, LR4 and 800GBASE-DR8 PAM4 optical transceivers, Chip on Board (COB) optical assemblies, and silicon photonics (SiPh). The GN1814 is sampling now as wire-bondable bare die.

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
