Description
General
The STi5167 is the latest in the family of STBus set-top box ICs providing high-performance,
ow-cost system-on-chip (SoC) for MPEG processing in digital terrestrial STBs. It is derived
from the STi5107, with the addition of a DVB-T COFDM demodulator and supports multiple
platforms using a unified architecture. STi5167 is compatible with the latest CA advanced
security specifications.
The STi5167 delivers enhanced performance with respect to previous devices. Main
memory is based upon a single 16-bit external SDR or DDR SDRAM.
The display architecture of the devices is based upon a high performance blitter engine that
supports CLUT8 and RGB16STi5167 formats for background, video and OSD/graphics
displays. It makes the porting of middleware easier with improved rendering.
