Product details

622Mbps laser diode driver in 24-TQFN

The MAX3646ETG+T is a single-channel laser diode driver rated for 622Mbps data rate, designed for fiber-optic transmitter modules in SONET/SDH and Gigabit Ethernet applications. It delivers up to 100 mA bias current and 85 mA modulation current from a 2.97V to 3.63V supply, drawing 47 mA supply current. The 24-TQFN (4x4 mm) package with exposed pad provides a low-inductance thermal path to the PCB ground plane, critical for maintaining eye-diagram margin at 622 Mbps.

Supply rails and package integration

The 2.97V to 3.63V supply range allows the driver to run from a standard 3.3V rail with margin for ripple and load transients. Tape & Reel packaging (also available as Cut Tape) suits automated pick-and-place assembly for volume production.
