MN2WS0025 System Block Diagram
The MN2WS0025 is a single-chip HDTV system LSI
intended for use in DTV and STB applications in the United
States, Japan, and Europe. This chip can be used to design
a very low-cost yet highly featured product. With the built-in
CableCARD™ interface, the MN2WS0025 directly sup-
ports U.S. Plug-and-Play/OpenCable™.
This chip provides the back-end processing necessary for
receiving digital HDTV broadcasts: transport stream decod-
ing (TS), MPEG video and audio decoding, peripheral func-
tions, and system processing. A standard system requires
just two 128-Mbit DDR-SDRAM chips.
The chip supports the U.S. terrestrial standard (ATSC), the
Plug-and-Play/OpenCable™ standard, the Japanese ter-
restrial standard (ISDB-T), both Japanese satellite stan-
dards (ISBD-S and DVB-S), and other digital broadcast
specifications from around the world. The MN2WS0025
also includes the CableCARD™ interface for the U.S.
OpenCable™ specifications and the interface for European
DVB specifications.
To enhance system efficiency, the MN2WS0025 has the fol-
lowing internal peripheral I/O interfaces:
■ Three synchronous/asynchronous serial interfaces
■ Parallel (GPIO) interface
■ SD card interface
■ Two smart card interfaces
■ High-speed I/O port for MPEG-TS
■ IR remote control interface
■ Two I2C interfaces
■ NAND/NOR flash memory interface
An audio delay function is also built-in for synchronizing
audio and video when receiving analog broadcasts as part
of an integrated analog and digital system.
