Up to 2.5Gbps operation
25mA peak drive current
Separate modulation control
Separate output enable for laser safety
Differential inputs for data
75K ? input pulldown resistor
Designed for use with SY88923, SY88904 or SY88905
Available in a tiny 10-pin (3mm) MSOP
The SY88922 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 SY88922 utilizes the high performance bipolar
ASSET? technology.
