General Description
The TAT2814A1L is an RFIC for DOCSIS 3.0 Output
Sections, such as CMTS and Edge QAM. It combines a
low-reflection differential input stage, a variable gain
attenuator and an efficient output amplifier to provide
significant reduction in power consumption and PC
board space. It replaces circuitry requiring up to 10x the
board space and 2x the power.
The TAT2814A1L meets the stringent DOCSIS 3.0
output linearity specifications with extra margin to
overcome additional losses before the output connector.
The TAT2814A1L is packaged in an industry standard
7 x 7 mm 48-pin leadless SMT package and consumes
5 W between a +5 V input amplifier supply and an +8 V
output amplifier supply. The TAT2814A1L utilizes proven
GaAs pHEMT to optimize performance and cost. It
allows the designer to optimize output stage voltage to
significantly reduce power consumption in Edge QAM
applications.
