SY88932L
SY88932L is SONET/SDH LASER DRIVER manufactured by Micrel Semiconductor.
3.3V, 4.25Gbps SONET/SDH Laser Driver with Output Disable
General Description
The SY88932L is the smallest available laser driver with a programmable modulation current up to 60m A 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.
