CX24109-11Z,518

Video Processing Overview

The CX24109-11Z,518 is a highly integrated direct down-conversion digital satellite tuner designed for high-volume digital video, audio, and data receivers. It operates on a single +5 V supply and utilizes a zero-IF architecture to eliminate image reject filtering requirements. The device integrates an LNA, variable RF attenuator, quadrature downconverter, baseband amplifiers, tunable low-pass filters, and a local oscillator with an onboard VCO and synthesizer. It supports symbol rates from 1–45 MSps and is compatible with DVB and DSS standards.

Video Processing Feature Summary

• Zero-IF architecture eliminates the need for external image reject filtering
• Integrated local oscillator with onboard VCO and synthesizer requiring only a 5 V source
• Single +5 V power supply operation simplifies system design
• Integrated LNA and variable gain control blocks reduce bill of materials cost

Video Processing Applications

• DBS set-top boxes
• Commercial digital video, audio, and data receivers
• Digital VCRs

Video Processing Procurement Notes

Verify that the ordering suffix Z,518 corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm the package type matches the 48-pin eTQFP footprint defined in the mechanical specifications. Ensure compatibility with the host processor's serial interface voltage levels before finalizing procurement.

Video Processing Selection Notes

Select this component when designing a complete broadband satellite front-end solution intended for demanding satellite environments. It is specifically optimized for use alongside the CX24121 QPSK demodulator/FEC decoder. Consider this part if the design requires a simplified RF layout and reduced BOM cost through high integration of analog and RF functions.

Video Processing Part Context

This device belongs to the CX24109 family of digital satellite tuners manufactured by NXP Semiconductors. It serves as the primary tuning and down-conversion stage in satellite receiver architectures. The part is derived from earlier Conexant designs and maintains functional compatibility with established satellite reception standards.
