3V and 5V power supply options Available in a tiny 10-pin (3mm × 3mm) MSOP DESCRIPTION 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 device incorporates complementary open collector outputs with a capability of driving peak current of 30mA.
The resistor REXT must be placed between /OUT and V CC to dissipate the worst case power.
R SER 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 ...
