Description
The AK2571 is a single-chip solution for WDM Laser Diode Module applications. It integrates both ATC (Auto Temperature Control) and APC (AutoPower Control) functions in a small 64-pin LQFP or bare die package..

Features
■ Single ChipLSI that integratesAPC (Auto Power Control) andATC(AutoTemperatureControl)functions for WDM Laser Module
■ A controllingTEC(ThermalElectricalCooler)stabilizesthetemperatureofLDmoduleintherangeof+/-0.1°C by PID algorithm.
■ Parameters controlling Laser Diode are user programmable and stored in EEPROM
■ Internal Temperature Sensor detects on-chip temperature, enabling compensation internal and external components that may be affected by changing ambient temperature.
■ Autonomous operation (internal oscillator and logic).
■ Pin-selectable wavelength data fortunable laser diodes (four options).
■ Single 3.3V operation
■ 64-pin LQFP or Bare chip
