1 INTRODUCTION
1.1 DESCRIPTION
The STi4600 is a fully integrated Class A Dolby
AC-3 decoder capable of decoding both 5.1 and 2
Channels compatible with the DVD standard. The
device also decodes both MPEG1 and MPEG2
layers I and II Audio.
The device accepts a MPEG-2 PES stream, input
data can be entered either by a serial or parallel in-
terface. The control interface can be either I C or a
parallel 8-bit interface. No external DRAM is nec-
essary for a total of 35ms surround delays.
