Product data sheet Rev. 01 — 13 November 2008 2 www.DataSheet4U.net NXP Semiconductors CX24109 Digital Satellite Tuner General description The CX24109 is a highly integrated, direct down-conversion satellite tuner intended for high-volume digital video, audio, and data receivers. When combined with the CX24121 QPSK demodulator/FEC decoder, the chip set provides a complete broadband satellite front-end solution capable of operating from 1–45 MSps in the most demanding satellite environments. It is compatible with international standards such as DVB and DSS. The highly integrated CX24109 reduces the tuner BOM cost and simplifies the RF layout.
