Burst-Mode PON Controller
With Integrated Monitoring
General Description
The DS1863 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’s bias current, and a tem-
perature 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. Five ADC channels
monitor VCC, internal temperature, and three external
monitor inputs (MON1–3) that can be used to meet trans-
mitter and receive monitoring requirements.
