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
