Product details
Overview
GN3068-3EB6AN4E3 from Semtech is a 10km low-power limiting Receive Optical Sub-Assembly (ROSA) optimized for SFP+ LR modules operating at up to 11.3 Gbps. It integrates a high-sensitivity PIN photodiode with a 7 kΩ transimpedance amplifier, delivers -21 dBm (OMA) unstressed sensitivity, consumes only 94 mW, and features integrated RSSI functionality. It is designed for 1310 nm single-mode fiber links in 10GBASE-LR and OC-192 IR-2 applications.
For engineers reviewing the GN3068-3EB6AN4E3 datasheet, pinout, applications, or equivalent options, key selection criteria include its 94 mW power dissipation, -21 dBm OMA sensitivity at 11.3 Gbps, TO-46 coaxial package compatibility, RSSI output accuracy, and qualification for industrial temperature range (-40°C to +85°C).
Technical Context
The GN3068-3EB6AN4E3 implements a fully integrated limiting amplifier architecture with fixed-gain transimpedance stage and post-amplifier, delivering clean CML-compatible digital output. Its Rchip-based design ensures high manufacturing yield and stable performance across voltage and temperature variations without external gain control loops.
It operates from a single +3.3 V ±10% supply and includes on-chip RSSI circuitry that provides monotonic, temperature-compensated analog voltage proportional to received optical power. The device meets IEEE 802.3ae 10GBASE-LR stressed receiver sensitivity requirements and supports standard SFP+ MSA electrical interface timing.
