6/11/2004 - Conexant Systems, Inc. (NASDAQ: CNXT), the worldwide leader in semiconductor solutions for broadband communications, enterprise networks and the digital home, announced the availability of two new digital video broadcast (DVB) cable and satellite set-top box (STB) reference designs. The cost-effective cable platform is based on Conexant’s CX24147 TV decoder IC, a highly integrated design that enables manufacturers to significantly reduce bill-of-material (BOM) costs for basic cable STB receivers. The satellite reference design has been developed for high-performance, low-cost STB receivers worldwide. It is based on Conexant’s CX24142 single-chip direct broadcast satellite (DBS) TV decoder IC and CX24109 silicon tuner to provide a complete system solution. These platforms provide manufacturers with a competitive edge by allowing them to reduce design and development costs and rapidly deliver new products to market.
“By providing reference designs with everything needed to jump-start product development, manufacturers can create complete, cost-effective solutions that can be brought to market much more quickly than if they had to design their products from scratch,” said Jeff Crosby, vice president of Set-top Box Products for Conexant. “Based on our leading-edge integrated circuits and packaged with essential software, these designs greatly reduce design time and product costs, allowing the manufacturer to be more competitive in the consumer electronics market.”
The DVB cable reference design, which is based on Conexant’s CX24147 television decoder, can receive and process digital video broadcast signals over cable. The CX24147 includes an integrated voltage-controlled crystal oscillator (VCXO), complete system clock generation from a single crystal, and high quality 10-bit video digital-to-analog converters (DACs) that support direct drive of video output connectors without the need for additional buffering.
The DVB satellite STB reference design is based on Conexant’s CX24109 integrated digital satellite tuner and CX24142 single-chip television decoder IC. In addition to the features provided by the CX24147, the CX24142 includes an integrated QPSK demodulator and FEC decoder, and DiSEqC 2.x support for two-way communication between the STB and low noise block (LNB). The CX24109 satellite tuner is based on a proven direct-conversion, Zero-IF architecture, and includes an integrated low noise amplifier, an integrated variable baseband filter that provides optimal interference rejection, and an integrated local oscillator with on-chip voltage-controlled oscillator and synthesizer that further reduces the overall cost of a complete set-top box.
Both reference designs provide manufacturers with complete turnkey solutions including schematics, layout, a costed bill-of material, software drivers, royalty-free real-time operating system (RTOS), user interface, electronic program guide (EPG) and documentation. The reference designs also include support for various middleware, and SmartCard or DVB-CI based conditional access systems.
