APPLICATIONS

The SAA7215 integrated MPEG AVGD decoder is aimed at being used in MPEG digital TV applications. This decoder is primarily designed to be connected to a SAA7214 transport stream descrambler/demultiplexer/ microcontroller by means of glueless interfaces even though connections to other market demultiplexers and/or microcontrollers are possible. Compatibility is also targeted with the SAA7219 and with the successor of the T-MIPS family.

The SAA7215 can be used in any system where high-end

GENERAL DESCRIPTION

The SAA7215HS, SAA7216HS, SAA7221H is a MPEG-2 sourcedecoderwhichcombinesaudiodecodingandvideo decoding. Additionally to these basic MPEG functions it also provides means for enhanced graphics, background display and/or on-screen display as well as encoding of output video. Due to an optimized architecture for audio and video decoding, maximum capacity in external memory and processing power from the external CPU is available for graphics support.

Possible options are indicated in Table 1. graphics are needed (associated SDRAM can be extended to 32-Mbit) as well as in low cost systems (all functions can be enabled with only 16-Mbit of associated SDRAM).
