Description STi5107
1 Description
1.1 General
The STi5107 is the latest in the family of Omega2 set-top box ICs providing a highperformance, low-cost system-on-chip(SoC) for MPEG processing in cable, satellite or
digital terrestrial STBs. It is a pin compatible IC derived from the STi5105, that supports
multiple platform using a unified architecture. STi5107 is compatible with the latest CA
advanced security specifications.
The STi5107 delivers enhanced performance with respect to previous devices. Main
memory is based upon a single 16-bit external SDR SDRAM.
The display architecture of the device is based upon a high performance blitter engine that
supports CLUT8 and RGB16 formats for background, video and OSD/graphics displays. It
makes the porting of middleware easier with greater rendering.
