Overview
LASER DIODE DRIVER WTIH OUTPUT ENABLE FEATURES s s s s s s s s s Up to 1.
25Gbps operation 25mA peak drive current Separate modulation control Separate output enable for laser safety Differential inputs for data 75KΩ input pulldown resistor Single power supply Designed for use with SY88903 and SY88904 Available in a tiny 10-pin (3mm) MSOP SY88902 DESCRIPTION The SY88902 is a high speed current switch for driving a semiconductor laser diode in optical transmission applications.
The output current, or modulation current IMOD, is DC current controlled by IRSET, current through the resistor RSET.
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 REXT 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.
