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 20 Pad 4.0x4.0x0.85mm QFN Package 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 Key Features eliminating the need for an extra ONT supply. +12V Single Supply Operation +5V Configuration Optional Functional Block Diagram Efficient Power Consumption: 1.5W for +12V TIA POST AMP POST AMP Low Noise: 3.5pA/Hz Equivalent Input Noise Current Bias Cntrl NC OUT A BIAS OUT IN A (EINC) 20 19 18 17 16 Linearity: 65dBc CSO and 66dBc CTB at +22dBmV POST AMP TIA IN A 1 15 BIAS A RF Output per Channel (79-NTSC Equivalent TIA Channels) Gain POST AMP BIAS 1 2 14 Block OUT A 451218MHz Operational Bandwidth 27dB AGC Range with Recommended External Control NC 3 13 NC Circuitry Gain POST AMP BIAS 1 Best-in-Class +22dBmV per Channel RF Output 12 4 OUT B Block TIA Capability POST AMP TIA IN B 11 5 BIAS B Applications 7 8 9 10 6 xPON RF Overlay Video Receiver for FTTX Triplexer- Bias Cntrl TIA OUT B POST AMP POST AMP NC BIAS OUT IN B Equipped Optical Network Termination (ONT) and Top View RFoG Network Interface Unit (NIU) Ordering Information Part No. Description QPB8888SQ Sample Bag with 25 Pieces QPB8888SR 7 Reel with 100 Pieces QPB8888TR13 13 Reel with 2500 Pieces QPB8888PCK-2 12V Transformer Coupled EVB Output with 5 Piece Sample Bag QPB8888PCK-4 5V Transformer Coupled EVB Output with 5 Piece Sample Bag Data Sheet Rev E, April 29, 2019 Subject to change without notice - 1 of 12 - www.qorvo.com QPB8888 xPON Video Receiver Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Supply Voltage (VDD) +15V Operating Temperature 40 +85 C Storage Temperature Range 40 to +150C Junction Temperature +160 C Exceeding any one or a combination of the Absolute Maximum Rating RF Power Supply Voltage +11.4 +12 +12.6 V conditions may cause permanent damage to the device.
