GN2042

Overview

The GN2042 is an integrated bi-directional CDR, DFB/FP laser driver and limiting amplifier designed

specifically to enable low power SFP+ re-timed modules for SONET.Based on the Semtech ClearEdge™

technology, the  GN2042 delivers best in class eye quality.

By integrating the laser driver, the GN2042 offers an extremely low-power solution for DML based optical

modules. It consumes only 636mW typical from a 3.3V supply and a 1.8V supply, with the laser driver

biased at 35mA bias current and 35mA modulation current.

Key Applications

• XFP & SFP+ 10Gb/s SONET optical transceivers

• XFP & SFP+ 10GBase-LR optical transceivers
