描述 Description

The QPB8888 is a 45 - 1200 MHz? High Gain Low EIN RF Optical Reciever for PON anmd RFOG applications.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 +23 dBmV / channel output to insure consistent video quality. It runs on a single +12 V supply eliminating the need for an extra ONT supply.
