Description STi5167

1 Description

1.1 General

The STi5167 is the latest in the family of STBus set-top box ICs providing high-performance, low-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.

The STi5167 is designed for CA applications with embedded HW security. Its BGA package allows the use of a simple 2-layer PCB, with all signals and power supplies

being routed through the top PCB layer. This leaves the bottom PCB layer dedicated to the ground plane and JTAG connections.
