DS1865 PON Triplexer Control and Monitoring Circuit

The DS1865 controls and monitors all the burst-mode transmitter and video receiver biasing functions for a passive optical network (PON) triplexer. It has an APC loop with tracking-error compensation that provides the reference for the laser driver bias current and a temperature-indexed lookup table.
