description sti5105 2/5 1 description stmicroelectronics sets a new standard for performance, price and integration in the single chip mpeg-2 set-top box decoder market with the introduction of the sti5105. this highly integrated solution targets mass market stbs, offers increased performance over earlier devices, and includes many features to further reduce costs, including a unified memory architecture. the sti5105 features the st20 cpu that is standard across the omega range but boosts the clock speed to 200 mhz which, when combined with the 2d graphics engine, gives the new device outstanding graphics performances. targeting low-cost, single tuner stb applications, the sti5105?s ddr memory interface both reduces system costs and minimizes overall system latency, ensuring the new device can support the most demanding interactive tv applications and middlewares. the integration of vcxo and audio dacs ensures that manufacturers using the sti5105 cut their bill of materials and significantly simplify board design and assembly. sti5105 is supplied in either 24 mm x 24 mm lqfp216 or 23 mm x 23 mm bga package.
