APC circuit laser diode driver IC

The SY88905 is an integrated control circuit for laser diode modules intended for high-frequency fiber-optic applications. The device is designed to operate with the SY88902 laser diode driver providing Automatic Power Control (APC) which provides bias current control and monitor. Laser diode pulse driver iC-NZN allows CW oper- An averaging current monitor can be set by means of ation of laser diodes and spike-free switching with an external resistor at pin RSI. When the current limit defined current pulses up to 155MHz. The SY88905 is designed to provide the laser diode with an independent DC threshold current (IBIAS) source to assure. ELM185xB is a bipolar type laser diode driver IC with internal APC circuit which consists of a reference voltage source, an error amplifier, and a thermal shutdown circuit for protection. Fluctuations in temperature, aging effects, and variations in external conditions can cause instability in laser performance. APC. This White Paper describes the design of fast driver circuits, PCB layouts and optical measurement considerations, as well as a solution to achieve an ideal design for pulses as short as 2.
