M02172

11.3Gbps EML Driver

Overview

Description

The M02172 is designed to drive Electroabsorption Modulated Lasers with a 50 ohm characteristic impedance used in Transmitter optical sub-assemblies. In EML applications, the programmable offset adjustment is integrated into the signal output. Output bias (offset) voltage which varies linearly as a function of temperature is provided as required by some EML devices.

The M02072 combines a diagnostic monitoring interface compliant with XFP, or SFP+ and a EML driver in a compact 5mm x 5mm QFN package. Integrated safety circuitry provides latched bias current and modulation voltage shutdown if a fault condition is detected. The device comes with firmware required for diagnostic monitoring, offering a seamless interface for calibration and setup.
