DVB-S FTA/CI/CAS Satellite Set-top Box Reference Design

Conexants portfolio includes a comprehensive suite of semiconductor solutions for Broadband Communications enterprise networks, and the digital home. The DVB-Satellite (DVB-S) set-top box (STB) reference design features a complete design package, including full software solution, using Conexants CX24142 satellite system-on-chip (SoC) and supports free to air (FTA) set-top boxes worldwide, including options for DVB-Common Interface (DVB-CI) and Smart Card-based conditional access systems (CAS). The system receives and down converts QPSK satellite digital Video signals to baseband with the CX24109 RF Tuner The CX24142 includes an integrated 150 MIPS ARM920T main system processor and performs the QPSK demodulation, MPEG-2 Audio and Video decode, and TV encoder functions. The integrated DiSEqC 2.x LNB signal generator, 10-bit Video DACs VCXO power-on reset circuitry, direct drive of Video output connectors and Clock generation from a single crystal, coupled with a two-layer PCB and low-cost front panel design, effectively reduces the system bill of material (BOM) cost for set-top box manufacturers.
