DS1862 - XFP Laser Control and Digital Diagnostic IC
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
