www.DataSheet4U.com Set-top Box Solutions Satellite DVB-S FTA Satellite Set-top Box Reference Design Featuring the CX24138 DVB Decoder and CX24109 Satellite Tuner IC Conexant’s 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 reference design features Conexant’s CX24109 RF tuner and CX24138 satellite system-onchip (SoC) to provide a low-cost, high-featured, complete system solution. The system receives and down-converts quadrature phase-shift keying (QPSK) satellite digital video signals to baseband with the CX24109 RF tuner. The CX24138 includes an integrated ARM920T ® main system processor running at 100 MHz, integrated QPSK demodulator, MPEG-2 audio and video decode, and TV encoder functions. The integrated 10-bit video DACs, integrated voltage-controlled crystal oscillator (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 reduce the system bill of material (BOM) cost for STB manufacturers. Conexant offers a complete reference design package integrating the CX24138 with the CX24109 tuner and an unprecedented level of localized design and sales support to accelerate development time-to-market.
