BASEL, Switzerland--(BUSINESS WIRE)--ECOC 2022 -- Semtech Corporation (Nasdaq: SMTC), a leading global supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, announced the immediate availability of the GN1816, a new addition to the FiberEdge® platform of PAM4 TIAs.

The introduction of the FiberEdge GN1816 TIA expands the Semtech FiberEdge portfolio into the short-reach data center space and enables customers to achieve an even smaller footprint for very high-density single mode fiber applications,” said Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “The FiberEdge GN1816 offers the industry-leading and trusted performance that characterizes all Semtech FiberEdge TIAs, easing the design and development cycles for optical module manufacturers and top hyperscale data center operators.”

The FiberEdge GN1816 is a 56GBd quad 250μm-pitch low power, low cost, low noise and high gain TIA, designed for 400GBASE-SR4/VR4 and 800GBASE-SR8/VR8 PAM4 multimode optical transceivers, as well as 400GBASE-DR4/FR4/LR4 and 800GBASE-DR8/FR8/LR8 PAM4 single mode optical transceivers. Additionally, the FiberEdge GN1816 works with active optical cable (AOC), Chip on Board (COB) optical assemblies and silicon photonics (SiPh).

Coupled with the recently introduced FiberEdge GN1848 quad VCSEL driver, the small die size of the FiberEdge GN1816 enables re-use of existing fiber coupling arrangements already used at lower bit rates. The FiberEdge GN1816 is sampling now as wire-bondable bare die.

Semtech’s FiberEdge platform 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
  • New – GN1816: 250um Pitch Quad 56GBd PAM4 Linear TIA
  • GN1848: Quad 56GBd PAM4 Linear VCSEL Driver
  • GN1862: Single Channel 56GBd PAM4 Linear EML Driver

The FiberEdge GN1816 will be demonstrated at the Semtech booth #322 during the European Conference on Optical Communication (ECOC) 2022, Sept. 18-22, in Basel, Switzerland. Register here.
