SY88932L 3.3V, 4.25Gbps SONET/SDH Laser Driver with Output Disable General Description Features The SY88932L is the smallest available laser driver with a Up to 4.25Gbps operation programmable modulation current up to 60mA for Fabry- Modulation current to 60mA Perot (FP) or distribution feedback (DFB) lasers. The Rise/fall times 65ps typical device is suitable for SOENT/SDH applications with data Input 50 internally terminated to VCC rates up to 4.25Gbps. The SY88932L accepts either CML level or AC-coupled PECL inputs, and incorporates an TTL /EN with internal 75k pull-down active low TTL /EN function which shuts off the modulation Designed for use with MIC3000 optical transceiver current when HIGH. management IC Datasheets and support documentation can be found on Voltage programmable laser modulation current Micrels web site at www.micrel.com.
