Set-top Box Solutions Satellite Digital Satellite Tuner RF IC CX24113 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 CX24113 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 CX24113 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. It has a standalone low-noise amplifier (LNA) that can be used for a loop-through design or can provide enhanced sensitivity for free-to-air applications. The device has an improved power supply rejection ratio (PSRR), requires a single +3.3V supply, and features very low power consumption. The CX24113 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 copper telephone lines.
