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.
