TAT6254C 光纤到户RF放大器, 50-1000MHz

The TriQuint TAT6254C FTTP SFU Video Receiver provides a low noise analog interface to CATV receivers and optical triplexers. The TAT6254C is intended for use in single family unit (SFU) analog video fiber to the premise (FTTP) applications. The TAT6254C exhibits low input noise and distortion that provides performance margin critical to meeting stringent FTTP link requirements. It runs on either a single 12 V or 5 V supply, eliminating the need for an extra ONU power supply. The TAT6254C provides automatic gain control (AGC) to maintain a constant +19 dBmV/ch output (+23 dBmV in high output mode) to ensure consistent video quality and ease of design. The TAT6254C is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. The TAT6254C has the flexibility to be designed for a range of RF outputs and supply voltages. This datasheet discusses four configurations; standard RF output and high RF output with both 5V and 12V supplies.
