Product data sheet
Input
RF
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.
