SAA7212 - Integrated MPEG AVG decoder

General Description

The SAA7212 is an MPEG2 source decoder which combines audio decoding and video decoding.

Additionally to these basic MPEG functions it also provides means for enhanced graphics and/or on-screen display (OSD).

Key Features

  • General features.
  • Single external Synchronous DRAM organized as 1 M × 16 interfacing at 81 MHz. Due to efficient memory use in MPEG decoding, more than 1 Mbit available for graphics.
  • Fast 16-bit data + 8-bit address interface with external controller on 27 MHz. Sustained data rate to external SDRAM ≤9 Mbytes/s in bursts of 128 bytes.
  • Dedicated input for audio and video in PES or ES in byte wide. Data input rate: ≤9 Mbytes/s in byte mode. Accompanying strobe signals dis.
