SY88932L中文资料Laser Diode Drivers数据手册Microchip规格书

描述 Description

The SY88932L is the smallest available laser driver with a programmable modulation current up to 60mA for Fabry-Perot (FP) or distributed feedback (DFB) lasers. The device is suitable for SONET/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.
