The SY88702 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 SY88702 incorporates complementary open collector outputs with 25mA 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.
The SY88702 utilizes the high performance bipolar ASSET™ technology.
