RFRX8888
The RFRX8888 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 RFRX8888 exhibits low input noise and
distortion to meet critical FTTP link requirements. RFRX8888, with
recommended external control circuitry, provides automatic gain
control to maintain a constant +19 to +23dBmV/channel output to
insure consistent video quality. It runs on a single 12V supply
eliminating the need for an extra ONT supply.
