CX24118

Set-top Box Solutions Satellite Digital Satellite Tuner RF IC CX24118 Supports Advanced Modulation Applications Conexant’s portfolio includes a comprehensive suite of semiconductor solutions for broadband communications, enterprise networks and the digital home. The CX24118 is Conexant’s third generation direct down-conversion satellite tuner RF IC intended for high-volume digital video, audio, and data receivers. The CX24118 offers excellent phase noise performance and very low implementation loss, required for advanced modulation systems such as 8PSK and DVB-S2. The CX24118 has a built-in auto-tuning machine that eliminates the need for software calibration routine and accelerates the calibration time. The on-chip fractional synthesizer enables fine frequency step size without adversely affecting lock time. The CX24118 does not require a Balun, thus reducing external BOM cost. Its highly integrated design saves valuable board space and simplifies RF layout. Conexant has a broad portfolio of semiconductor products, including: DSL, dial-up, and cable modem solutions Home network processors Broadcast video encoders and decoders Digital set-top box components and system solutions Distinguishing Features w Conexant also offers wireless data and networking solutions that includes Zero-IF architecture eliminates the need for image reject filtering Very low phase noise for 8PSK and DVB-S2 applications Variable baseband filters for optimal interference rejection ...
