single-chip STBs CX2448x (DVB-C)
Complete system solutions advanced DVB-C platforms
Equipped with high-performance host premium features, these give manufacturers lowest system BoM. tuner, SDRAM, Flash memory that's required complete cutting-edge system.
Features MPEG-2/DVB-C decoder with integrated demodulator High-performance 32-bit ARM9 CPU: MIPS, 16-KB caches Advanced security hardware features NDS, Nagravision, Irdeto, Conax Latens High-performance graphics rendering acceleration Multiplane video/graphics compositing display engine High-performance 16-bit unified memory controller architecture Integrated bridge controller memory interface High-speed interface This family, which includes powerful MPEG-2 decoder DVB-C set-top boxes (STBs), specially designed give manufacturers broadcast service providers highest levels performance format that saves space, cuts design time, lowers overall cost. family same basic architecture, built around 32-bit ARM926 CPU, running capable delivering MIPS. also includes demodulator, programmable transport stream processor, MPEG-2 audio/video decoder, advanced graphics hardware accelerator, display controller, audio DAC, encoder, memory interface, high-speed interface. very high level integration significantly reduces external component count. only extra hardware needed complete high-end tuner cable half-NIM), DDRSDRAM, Flash memory.
integrated demodulator complies with SCTE-40 specifications supports 16/32/64/128/256 modes Annex A/Annex cable systems. interfaced TDA18252 tuner most cable half-NIMs market. Transport Stream Processor process MPEG-2 compliant transport streams peak data rate Mbps, supporting filtering PIDs. hardware coprocessor handles high data throughput functions such descrambling, CRC, assistance section filtering. architecture also uses encoder support NTSC, SECAM standards. There 10-bit video DACs, simultaneous output CVBS, S-Video, YPbPr. enable rich navigation user interfaces, integrate advanced graphics hardware accelerator five graphic display panels. They designer combine MPEG video, external video, graphics OSD, teletext, cursor data implement advanced display functions. very high performance enables interactive features like advanced EPGs, online games, shopping, interactive polling. configured sophisticated middleware that runs downloadable applications
using high-speed return channel. return channel connect, interface, Ethernet MAC/PHY controller DOCSIS Advanced security cable operators Several features give broadcasters level protection against piracy. advanced one-time-programmable (OTP) memory technology lets broadcasters personalize individual STBs with unique serial numbers encryption keys, transactions between smart card broadcaster service decoder more secure. also embedded cryptographic technology secure authentication system software loaded into Flash memory. family supports major vendor requirements, including NDS, Nagravision, Conax, Latens Irdeto. Full-featured development platform These devices part fully engineered, interactive development systems. hardware platform comes equipped with fully integrated Nucleus+ Linux driver software components. mature robust hardware abstraction layer assured re-use core driver libraries developed early generation ICs. development platform set-top hardware designed with two- four-layer configurations, plus variety return channel configurations.
