The SY88922V 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 when output enable is HIGH.
The SY88922V incorporates complementary open collector outputs with a capability of driving peak current of 30mA. 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. Pin 9 and pin 10 should be connected to achieve better performance.
The SY88922V utilizes the high-performance bipolar ASSET technology.All support documentation can be found on Micrel's web site at www.micrel.com.
