Overview
com Rev 0; 2/06 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 average power control (APC) and allows extinction ratio control though a temperature indexed look-up table (LUT).
The DS1862 monitors up to seven analog inputs, including temperature 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 tolerance.
Calibration is also provided internally using independen...
