description STI5118 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 STI5118. this highly integrated solution targets mass market fta set-top boxes, offers increased performance over earlier devices and includes many features for further reduce costs, including a unified memory architecture. the STI5118 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, for mosaic composition, fast channel change time and richer graphic content. targeting low-cost, single tuner stb applications, the STI5118 is hardware and software binary compatible with the sti5105. this allows manufacturers to use a unified platform for all mass market set-top boxes. the integration of the vcxo and audio dacs ensures that manufacturers using the STI5118 will cut their total bill of materials and significantly simplify board design and assembly.
