TAT6254B Qorvo

TAT6254B Fiber To The Home RF Amplifier 47 1000 MHz Applications High dynamic range FTTH RFoG (Radio Frequency over Glass) and GPON FTTH Multi Dwelling Unit TIA Mini-node Product Features Functional Block Diagram Pin compatible with the TAT6254C Single 12 V configuration Low Noise 3.0 pA/rtHz Equivalent Input Noise 14 dBmV/channel RF output at 55.25 MHz Both RF and Optical AGC designs available, continuously variable Low power consumption, 1.2 Watts at 12 V -12 to -2 dBm optical input range Linearity better than 62 dBc CSO and 62 dBc CTB General Description Pin Configuration The TriQuint TAT6254B FTTP SFU Video Receiver Pin Symbol provides a low noise analog interface to CATV receivers 1 TIA IN A and optical triplexers. The TAT6254B is intended for use 2,4 BIAS 1 3,13 NC in single family unit (SFU) analog video fiber to the 5 TIA IN B premise (FTTP) applications. 6 BIAS ADJ B 7 TIA OUT B The TAT6254B exhibits low input noise and distortion 8, 18 BIAS 2 that provides performance margin critical to meeting 9 PA IN B stringent FTTP link requirements, particularly those with 11, 12 PA OUT B all QAM channel loading. It runs on a single 12 volt 14, 15 PA OUT A supply, eliminating the need for an extra ONU power 17 PA IN A supply. The TAT6254B provides automatic gain control 19 TIA OUT A 20 BIAS ADJ A (AGC) to maintain a constant +14 dBmV/ch output to EPAD GND ensure consistent video quality and ease of design. The TAT6254B is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. The TAT6254B is pin and functionally compatible with the TAT6254C, though it has significantly increased gain and lower noise for all or near-all QAM deployments.
