STI5518

® CO n n SINGLE-CHIP SET-TOP BOX DECODER WITH MP3 AND HARD DISK DRIVE SUPPORT DATA SHEET The STi5518 is a highly integrated single-chip decoder, designed for use in feature-rich mass-market set-top boxes. It integrates a high-performance 32-bit CPU, a dedicated block for DVB/DirecTV transport demultiplexing and descrambling, modules for MPEG-2 video and audio decoding with 3D-surround and MP3 support, advanced display and graphics features, a digital video encoder and all of the system peripherals required in a typical low-cost interactive receiver. To cover the needs of DVD-capable set-top boxes, STi5518 integration options include a CSS decryption block, a Dolby Digital audio decoder and Macrovision copy protection. An ATAPI interface is built-in, supporting the glueless connection of standard Hard Disk Drives. In this way, the STi5518 is ideal for set-top boxes featuring trick modes such as live TV recording, pausing and time-shifting. The STi5518 is backward compatible with the popular STi5500 set-top box decoder, allowing easy migration from the previous generation. The high level of integration in a single PQFP-208 package makes the STi5518 ideally suited for low-cost, high-volume set-top box applications.
