General Description
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 (LUT)
that controls the modulation current. It continually monitors for high output
current, high bias current, and low and high transmit
power with its internal fast comparators to ensure that laser shutdown for eye
safety requirements are met with
out adding external components.
