Digital Satellite Tuner RF IC
CX24113A
Highly Integrated, Worldwide Broadband Satellite
Front-End Solution
Conexant’s portfolio includes a comprehensive suite of semiconductor solutions for
broadband communications, enterprise networks and the digital home. The CX24113A
is Conexant’s third generation direct down-conversion satellite tuner RF IC intended
for operator-based digital satellite networks and free-to-air systems. The CX24113A is
a highly integrated satellite tuner solution that incorporates an advanced Fractional-N
synthesizer, I2C serial interface, a fully integrated local oscillator, and variable baseband
filters. The device has an improved power supply rejection ratio (PSRR), requires a
single +3.3V supply, and features very low power consumption.
The CX24113A has a built-in auto-tuning machine that eliminates the need for software
calibration and accelerates the calibration time. The on-chip fractional synthesizer
enables fine frequency step size without adversely affecting lock time. The CX24113
does not require a balun, thus reducing external bill of materials (BOM) cost. Its highly
integrated design saves valuable board space and simplifies RF layout.
The company’s broad portfolio of semiconductor products also includes client-side xDSL
and cable modem solutions, home network processors, broadcast video encoders and
decoders, digital set-top box components and systems solutions, and dial-up modems.
In addition to its IEEE 802.11a/b/g-compliant WLAN chipsets, software and reference
designs, Conexant offers a suite of networking components that includes solutions
for applications based on HomePlug® and HomePNA™. Additional products include a
complete line of asymmetric and symmetric DSL central office solutions, which are
used by service providers worldwide to deliver broadband data, voice, and video over
w copper telephone lines.
