SY88932L_08 Datasheet, PDF (1/7 Pages) Micrel Semiconductor – 3.3V, 4.25Gbps SONET/SDH Laser Driver with Output Disable

SY88932L
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 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.
