CX24138 Datasheet | Conexant Systems

.. 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 prehensive suite of semiconductor solutions for broadband munications, 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 (So C) to provide a low-cost, high-featured, plete 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 plete 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. The DVB-S free-to-air (FTA) satellite STB reference design kit includes samples, schematics, layout, BOM, STB drivers, scan algorithm, user interface with Chinese and English language support, and plete documentation of the hardware and software system solution. The pany’s broad portfolio of semiconductor products also includes client-side digital subscriber line (DSL) and cable modem solutions, home network processors, broadcast video encoders and decoders, digital set-top box ponents and systems solutions, and dial-up modems. In addition to its IEEE 802.11a/b/g-pliant wireless local area...
