Set-top Box Solutions Satellite Set-top Box Solutions Satellite Product of the Year Award Winner Best Silicon Innovation Dual Decode HDTV MPEG-2/H.264/VC-1 Video Decoder CX2427x Conexant’s portfolio includes a comprehensive suite of semiconductor solutions for broadband communications and the digital home. Conexant’s CX2427x is a highly integrated, triple-display dual decode MPEG-2/H.264/VC-1, DIRECTV/DVB compliant, back-end decoder IC solution for high-definition digital TV systems with support for personal video recorder (PVR) applications, which can be deployed in digital satellite, cable, Telco or terrestrial TV networks. The CX2427x family features a flexible, multi-program HDTV multi format video decoder capable of decoding two HDTV programs simultaneously in any dual stream combination of MPEG-2, H.264 and VC-1 formats. Three TV outputs are supported, a primary HDTV display with simultaneous down-converted SD output, plus an independent down-converted NTSCL/PAL SDTV output. The dual multi-format audio decoder supports multiple audio format decoding, including MPEG-1, MPEG-2, Dolby® Digital, Dolby Digital+. MPEG-4 aac and aacPlus™, WMA and WMA Pro. An integrated ARM1176 CPU with 128KByte L2 cache supplying over 800 Dhrystone 1.2 MIPS at 666MHz, and a high performance, unified memory, dual 667MHz 32-bit DDR-2 SDRAM memory controllers give ample processing power for advanced applications and future expansion capability. each of which is based on a dedicated RISC engine, with each supporting six • Dual PVR support with dual SATA-2/eSATA-2 interface simultaneous transport streams (3 from baseband inputs and 3 from DMA • Multiple OS support including Nucleus+, VxWorks, Linux® and Windows® CE access system.
