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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
