SAA7212 - NXP

SAA7212 Integrated MPEG AVG decoder

SAA7212 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). Due to an optimized architecture for audio and video decoding, maximum capacity in external memory and processing power from the external CPU.

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 distinguish between audio and video data
• Dedicated compressed data input compatible with the VLSI VES2020/2030 demultiplexers.
