XFP Laser Control and Digital Diagnostic IC

General Description

The DS1862 is a closed-loop laser-driver control IC with

built-in digital diagnostics designed for XFP MSA. The

laser control function incorporates automatic power

control (APC) and allows extinction ratio control though

a temperature-indexed lookup table (LUT). The DS1862

monitors up to seven analog inputs, including tempera-

ture and monitor diode (MD) current, which are used to

regulate the laser bias current and extinction ratio.

Warning and alarm thresholds can be programmed to

generate an interrupt if monitored signals exceed toler-

ance. Calibration is also provided internally using inde-

pendent gain and offset scaling registers for each of

the monitored analog signals. Settings such as pro-

grammed calibration data are stored in password-pro-

tected EEPROM memory. Programming is accomplished

through an I

C-compatible interface, which can also be

used to access diagnostic functionality.
