Overview

ASAHI KASEI [AK2570] AK2570 Feed Forward APC LSI for LD Module DESCRIPTION AK2570 is the monolithic CMOS LSI has the function of ‘ Feed Forward Automatic Power Control (APC)’ for the Laser Diode (LD) module and maintains the emission intensity of the LD module constant with the high accuracy.
For stabilizing the emission intensity of the LD module affected by the ambient temperature, AK2570 feeds the compensation voltage from the 2channels - 8bits D to A converter to control the Bias- and the Modulation- current for the LD module.
The compensation voltage corresponds to the temperature characteristic data of the LD module retained in the on-chip EEPROM and the ambient temperature detected ...
