5V/3.3V 155Mbps Micrel SY88822V LASER DIODE DRIVER SY88822V WITH OUTPUT ENABLE FEATURES DESCRIPTION Single 3.3V or 5V power supply The SY88822V is a high speed current switch for driving a semiconductor laser diode in optical transmission Up to 155Mbps operation applications. The modulation current (IOUT) is controlled by Modulation current to 30mA the current (IRSET) through the external resistor RSET. The PECL output enable output OUT is HIGH and no current flows through OUT Differential PECL inputs when output enable is HIGH. Available in a tiny 10-pin (3mm) MSOP The device incorporates complementary open collector outputs with a 30mA maximum current driving capability. The external resistor REXT must be placed between /OUT and VCC to dissipate the worst case powe
