XFP Laser Control and Digital Diagnostic IC
General Description
The DS1862A is a closed-loop laser-driver control IC
with built-in digital diagnostics designed for XFP MSA.
Features
? Implements XFP MSA Requirements for Digital
Diagnostics, Serial ID, and User Memory
The laser control function incorporates automatic power
control (APC) and allows extinction ratio control though
a temperature-indexed lookup table (LUT). The
DS1862A monitors up to seven analog inputs, including
?
?
?
I 2 C-Compatible Serial Interface
Automatic Power Control (APC)
Extinction Ratio Control with Lookup Table
temperature and monitor diode (MD) current, which are
used to regulate the laser bias current and extinction
ratio. Warning and alarm thresholds can be pro-
grammed to generate an interrupt if monitored signals
exceed tolerance. Calibration is also provided internally
using independent gain and offset scaling registers for
each of the monitored analog signals. Settings such as
programmed calibration data are stored in password-
protected EEPROM memory. Programming is accom-
plished through an I 2 C-compatible interface, which can
also be used to access diagnostic functionality.
? Seven Monitored Channels for Digital Diagnostics
(Five Basic Plus Two Auxiliary)
? Internal Calibration of Monitored Channels
(Temp, V CC2/3 , Bias Current, Transmitted, and
Received Power)
? Programmable Quick-Trip Logic for Turning
Off Laser for Eye Safety
? Access to Monitoring and ID Information
? Programmable Alarm and Warning Thresholds
? Operates from 3.3V or 5V Supply
