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.
