It is a highly integrated solution suitable for DVB-C or DVB-T/IP STB markets worldwide. The STi5251 provides a solution for operators to specify a range of cost-effective SD STBs including high-volume broadcast-only zapper STBs, interactive STBs and dual-stream DVR and time-shift capable STBs. Content delivery is possible using broadcast and Ethernet connectivity (Hybrid STBs). The STi5251 is optimized for secure Pay-TV applications with integrated DVB, DES, AES, TDES and ICAM descramblers and smartcard interfaces. It also has advanced security features to further safeguard operator and content investment including secure control words, software integrity checking, JTAG locking and DRM support. The STi5251 offers high-performance CPU and graphics subsystem, which targets the full range of software/UI platforms from basic OS/program guide to demanding middlewares, such as MHP. 2/4 Features Benefits Combines a DVB-C/DVB-T demodulator with STB decoding and display functions This highly integrated SoC helps to reduce board area and manufacturing cost, allowing cost effective and small-size STBs to be designed for DVB-C/DVB-T networks Serial Flash-based secure boot and code storage, integrated voltage regulator, 23 mm x 23 mm x 1.7 mm PBGA package Enables further BOM optimization and cost reduction of advanced decoding SD STBs ST40-300 applications CPU @450 MHz, 32 K I cache, 32 K D cache Up to 800 DMIPs superscalar performance from a single CPU core, using standard tools and operating systems (Linux, OS21) STMicroelectronics' DELTA video decoding system with ST231 processor Decoding of advanced standard definition MPEG2, H.264 and VC-1/WMV9 streams, with the performance and flexibility for web-based content decoding such as Flash, DivX, MJPEG, XviD and Real Dual USB 2.0 hosts, Ethernet MAC with MII/RMII and TMII, SD-MMC/SDIO Extensive high-speed connectivity for the widest range of STB peripherals, such as Flash drives, external HDDs, home network controllers (for example MoCA, Wi-Fi), memory cards Low power process, design and architecture Best in class, low-power standby mode, to meet emerging energy standards for STBs. Dynamic configuration of power to individual subsystems enables power-efficient active standby modes Advanced 2D graphics and display subsystem and 480p/576p display output Allows visually appealing user interfaces and video-rich navigation to be offered to consumers, while high-quality progressive output can be watched on the latest displays Doc ID 022143 Rev 1 STi5251 2 Revision history Revision history Table 1.
