General Description

The SY88932L is the smallest available laser driver with a

programmable modulation current up to 60mA for Fabry-

Perot (FP) or distribution feedback (DFB) lasers. The

device is suitable for SOENT/SDH applications with data

rates up to 4.25Gbps. The SY88932L accepts either CML

level or AC-coupled PECL inputs, and incorporates an

active low TTL /EN function which shuts off the modulation

current when HIGH.

Datasheets and support documentation can be found on

Micrel’s web site at www.micrel.com.
