Product details
Overview
GN3357-3EB9AN4E3 from Semtech is a 11.3 Gbps high-gain APD-based Receive Optical Sub-Assembly (ROSA) featuring a linear automatic gain control (AGC) transimpedance amplifier (TIA), optimized for 80 km limiting and DWDM applications requiring excellent optical signal-to-noise ratio (OSNR) performance. It operates at +3.3 V ±10%, delivers -27 dBm unstressed sensitivity (OMA), and integrates patented Rchip technology for high manufacturing yield in SFP+ modules.
For engineers reviewing the GN3357-3EB9AN4E3 datasheet, pinout, applications, or equivalent options, key selection criteria include APD bias voltage control (VAPD), linear AGC TIA architecture, -27 dBm OSNR-limited sensitivity, and compatibility with 1310 nm / 1550 nm DWDM and long-reach 10G Ethernet systems.
Technical Context
The GN3357-3EB9AN4E3 implements a linear AGC TIA architecture with 8.5 kΩ transimpedance gain and 11.3 Gbps bandwidth, enabling operation in low-OSNR DWDM environments where constant-amplitude output and dynamic range preservation are critical. Its APD integration supports high-sensitivity reception without external post-amplification.
Designed for compliance with IEEE 802.3ae 10GBASE-LR/ER and ITU-T G.987 XG-PON OLT receiver requirements, the ROSA includes on-chip RSSI functionality and supports programmable VAPD control to optimize APD responsivity across temperature and aging.
