QPB8888
®
xPON Video Receiver
Product Overview
The QPB8888 is a video receiver integrated circuit (IC)
which provides a low noise analog interface to optical
access triplexer modules used in single family ONTs in fiber
to the premise (FTTP) applications. The QPB8888 exhibits
low input noise and distortion to meet critical FTTP link
requirements. QPB8888, with recommended external
control circuitry, provides automatic gain control to maintain
a constant +19 to +23ꢀdBmVꢀ/ꢀchannel output to insure
consistent video quality. It runs on a single +12ꢀV supply
eliminating the need for an extra ONT supply.
