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
Conexant also offers wireless data and networking solutions that includes
w HomePlug, HomePNA, and WLAN (802.11) components and reference designs.
