General Description
The TriQuint TAT6254B FTTP SFU Video Receiver
provides a low noise analog interface to CATV receivers
and optical triplexers. The TAT6254B is intended for use
in single family unit (SFU) analog video fiber to the
premise (FTTP) applications.
The TAT6254B exhibits low input noise and distortion
that provides performance margin critical to meeting
stringent FTTP link requirements, particularly those with
all QAM channel loading. It runs on a single 12 volt
supply, eliminating the need for an extra ONU power
supply. The TAT6254B provides automatic gain control
(AGC) to maintain a constant +14 dBmV/ch output to
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.
