Preliminary speciﬁcation

Integrated MPEG AVGD decoders

SAA7215; SAA7216; SAA7221

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

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).

GENERAL DESCRIPTION

The SAA7215HS, SAA7216HS, SAA7221H is a MPEG-2

source decoder which combines audio decoding and video

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.
