DESCRIPTION
- MACROVISION™ VERSION 7.01/6.1
COMPATIBLE
The STi5500 is the first of a new generation of
integrated multimedia decoder engines for set top
- TELETEXT, AND CLOSED CAPTION
box and DVD applications. It offers a high level of
. - SIMULTANEOUS OUTPUT OF RGB, CVBS
AND COMPONENT VIDEO
HIGH PERFORMANCE SDRAM MEMORY
INTERFACE
- SUPPORTS 1 OR 2 16MBIT 100MHz SDRAMS
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.
- ACCESSIBLE BY MPEG DECODER, CPU
AND DMAS
- HIGH BANDWIDTH ACCESS FROM CPU
. ALLOWS HIGH PERFORMANCE OSD
OPERATIONS
PROGRAMMABLE MEMORY INTERFACE
- 4 BANKS EACH 8/16 BITS WIDE
.- SUPPORT FOR MIXED MEMORY,
PER I PH ERALS, DRAM AND POWER PC
LINK INTERFACE
- SERIAL INPUT
PQFP208
(Plastic Quad Flat Pack)
- SUPPORTS DSS, DVB, AND DVD
BITSTREAMS
ORDER CODE : STi5500
- 32 PIDS SUPPORTED
