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 temper-
ature-indexed lookup table (LUT) that controls the mod-
ulation 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. Six ADC channels
monitor VCC, internal temperature, and four external
monitor inputs (MON1–MON4) that can be used to meet
transmitter and video receive signal monitoring require-
ments. Two digital-to-analog converter (DAC) outputs
are available for biasing the video receiver channel, and
five digital I/O pins are present to allow additional moni-
toring and configuration.
