The SY88702 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 and no current flows through
OUT when output enable is HIGH.
The device incorporates complementary open collector
outputs with 25mA maximum current driving capability.
The external 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.
The SY88702 utilizes the high performance bipolar
ASSET technology.
ASSET is a trademark of Micrel, Inc.
