描述 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.
