Description
The AK2573A is a 1chip LDD (Laser Diode Driver) and
an APC (AutoPower Control) for laser direct
modulation application. It contains up to156M LDD,
programmable duty adjustment, BIAS and modulation
currents, a digital feedback circuit, BIAS and
modulation current monitors, failure alarms, I

interface, an EEPROM for storing LD characteristics
and user information, and TXFAULT detection for SFP
application. The AK2573A has two APC functions;
APC FF (Feed-forward) and APC FB (Feedback). APC
FF supplies a programmed current in response tothe
temperature. APC FB provides a stable auto power
contro function with an internal digital feedback
algorithm.
All program and operational functions can be set
through the I

compatible interface and stored in the
on-chip EEPROM.
