Microchip SY88822VKG

激光二极管驱动器（光纤）155Mbps3V ~ 3.6V，4.5V ~ 5.5V

Overview

The SY88822VKG is a high speed current switch for driving a semiconductor laser diode in optical transmission applications. The modulation current (IOUT) is controlled by the current (IRSET) through the external resistor RSET. The output OUT is HIGH and no current flows through OUT when output enable is HIGH.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 power. RSER is recommended to compensate for laser diode matching issues. Pin 9 and pin 10 should be connected to achieve better performance.The SY88822VKG utilizes the high performance bipolar ASSET technology.
