SY88902 - LASER DIODE DRIVER

General Description

The SY88902 is a high speed current switch for driving a semiconductor laser diode in optical transmission applications.

The output current, or modulation current IMOD, is DC current controlled by IRSET, current through the resistor RSET.

The output OUT is HIGH when output enable is HIGH.

Key Features
