SY88722V数据手册集成电路（IC）的激光驱动器规格书PDF

描述 Description

The SY88722V is a high speed current switch for driving a semiconductor laser diode in optical transmission applications. The modulation current (IOUT) is controlled by the current (IRSET) through the external resistor RSET. The output OUT is HIGH and no current flows through OUT when output enable is HIGH.The device incorporates complementary open collector outputs with a 30mA maximum current driving capability. The external 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. Pins 9 and 10 should be connected to achieve better performance.The SY88722V utilizes the high performance bipolar ASSET technology.
