easy to implement.
Highly Integrated, Direct Down-Conversion Satellite Tuner
Conexant’s broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. Combining extensive experience in broadband systems and mixed-
signal integrated circuit design, Conexant introduces the CX24109 Digital
Satellite Tuner – a highly integrated, direct down-conversion satellite tuner
intended for high-volume digital video, audio, and data receivers. The
CX24109 consists of an LNA, variable RF attenuator, quadrature
downconverter, variable IF gain amplifiers, variable low-pass filters, VCO,
and synthesizer. This highly integrated satellite tuner RF IC does not require
a balun, therefore simplifying RF layout and reducing the overall BOM cost.
When combined with Conexant’s CX24123 QPSK demodulator/FEC decoder,
the chipset provides a complete broadband satellite front-end solution capable
solution offered in a compact design that saves valuable board space and is
