DATA BRIEF
STM5118
Low-cost interactive FTA set-top box decoder
Rev. 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 STM5118. 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 STM5118 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 STM5118 is hardware and
software binary compatible with the STx5105. 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 STM5118 will
cut their total bill of materials and significantly
simplify board design and assembly.
