The SY88922V is a high-speed current switch for
driving a semiconductor laser diode in optical transmission
applications. The modulation current (I OUT ) is controlled
by the current (I RSET ) through the external resistor R SET .
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 R EXT 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 high-performance bipolar
ASSET? technology.
