General Description
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.
