SY88922V中文资料Laser Diode Drivers数据手册Microchip规格书

描述 Description

The SY88922 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.

The device incorporates complementary open collector outputs with a capability of driving peak current of 25mA.

The resistor REXT must be placed between /OUT and VCC to dissipate the worst case power. RSER is recommended to compensate for laser diode matching issues.

The SY88922 utilizes the high performance bipolar ASSET™ technology.
