The SY88922 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 o...
