Introduction
The STi5197 uses state of the art process technology to provide an ultra low cost, full featured, SD set-top box SOC. It is a highly integrated solution combining QAM demodulation, audio/video decoding and applications processing into a single chip, suitable for MPEG2 based Cable networks worldwide. The STi5197 provides a solution for operators to specify a range of low cost SD STBs including low cost Zappers, Interactive STBs and DVR-capable STBs, with content delivery using broadcast or broadband networks, or both (Hybrid STBs). The STi5197 is optimized for secure Pay-TV applications with integrated DVB, DES, Multi2 and ICAM descramblers and Smart Card interfaces. It also has advanced security features normally found in mid-to-high end devices to further safeguard operator and content investment. The STi5197 offers enhancements in performance, features and integration to current users of ST's MPEG2 SD family of audio/video decoders and QAM demodulators, whilst reducing cost and time-to-market for the next generation of deployments. Few external components are required to realize a complete STB solution, resulting in very low BOM cost.
Features Combines a configurable QAM demodulator with STB decoding and display functions Benefits This highly integrated SoC helps to reduce board area and manufacturing cost, allowing low-cost, small size STBs to be designed for DVB-S networks Up to 580 DMIPs superscalar performance from a single CPU core, using standard tools and operating systems (Linux, OS21) Allows dual SD decoding of MPEG2 video with PIP capability Enables connectivity to HDD for PVR systems and to Ethernet networks for IP TV and hybrid/IP STBs Low operating power consumption (<1W). Best in class, low power standby mode (0.1W). Fast resume from standby. Reduced board manufacturing costs and board size Allows low cost BOM, and safeguards boot code integrity
ST40-300 applications CPU @350MHz, 32K I cache, 32K D cache STMicroelectronics' Delta video decoding system with Blitter display Integrated USB 2.0 host, Ethernet MAC with MII/RMII, Low power process, design and architecture
Available in 15x15 package with ballout optimized for 2-layer PCBs Support for Serial Flash including secure boot.

Package options
The STi5197 is available in two package options, 15 mm x 15 mm LFBGA, 0.8 mm pitch and 23 mm x 23 mm PBGA, 0.8 mm pitch. Both package types are compatible with the design of two-layer PCBs.
15 mm x 15 mm PBGA, 0.8 mm pitch
This is the main stream, low cost option which does not include the EMI interface. Both Ethernet and USB 2.0 interfaces are still available. For this option the Flash used must be Serial NOR Flash attached to the High Speed SPI interface.
23 mm x 23 mm PBGA, 0.8 mm pitch
This option should be selected if a full specification device is required, which includes the EMI. Any Flash type (Serial NOR, Parallel NOR, NAND) can be used with this package. The following features are available with this package option:
All the features as in the BGA15 mm x 15 mm package DVB-CI support NAND Flash storage EMI interfaces available, Secure Boot from any Flash (Serial, NAND or NOR) HDD attachment via EIDE
With this package, DVB-CI and Ethernet are mutually exclusive options. Table 1. Comparison table
