The SY88902 is a high speed current switch for driving
a semiconductor laser diode in optical transmission
applications. The output current, or modulation current
I
MOD
, is DC current controlled by I
RSET
, current through
the 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 25mA.
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.
The SY88902 utilizes the high performance bipolar
ASSET technology.
