Overview: RFRX8888 RFRX8888
xPON Video Receiver 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. TIA POST AMP POST AMP Bias Cntrl OUT A BIAS OUT IN A 20 19 18 17 NC
