SY88932L

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 FabryPerot (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.
