208 PIN PQFP PACKAGE

DESCRIPTION

The STi5500 is the first of a new generation of

integrated multimedia decoder engines for set top

box and DVD applications. It offers a high level of

integration by reducing the complete set top box

decoding chain from Transport Demux to

PAL/NTSC Encoder onto one chip. At the same time

it dramatically enhances CPU and Graphics per-

formance, and cuts down total system memory cost.
