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 supports U.S. Plug-and-Play/OpenCable™.
This chip provides the back-end processing necessary for
receiving digital HDTV broadcasts: transport stream decoding (TS), MPEG video and audio decoding, peripheral functions, 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 terrestrial standard (ISDB-T), both Japanese satellite standards (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 following 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.
MN2WS0025 REFERENCE SYSTEM
Panasonic Semiconductor’s system board for the
MN2WS0025 provides a complete Plug-and-Play hardware
reference design to “jump-start” software development using
the Panasonic Semiconductor software development kit. We
provide source code for transport demux, MPEG AV decoding, Digital Dolby audio decoding, ITU-R BT.656 video capture, channel navigation user interface sample, nonvolatile
memory access, and simple command-line shell for debugging. Optional modules for Plug-and-Play/OpenCable™
and DTV closed captioning are also available.
The MN2WS0025 resides on the main (or back-end) board
and is the heart of the system. This board controls all other
functions in the system and performs transport, video and
audio decoding, video scaling, graphics compositing, ITU-R
BT.656 video capture, and video and audio output. The reference system also includes a front-end board that provides
the tuning and demodulation for Plug-and-Play/
OpenCable™, terrestrial ATSC and NTSC, and inputs for
S-video, composite video, and L/R audio.
A front panel board receives and decodes IR commands
and scans the front panel buttons. This board has the capability to emulate a TV microcontroller by acting as an I2C
master while the main board is an I2C slave, simplifying the
use of MN2WS0025 as a plug-in DTV module for an existing NTSC television.

ABOUT PANASONIC SEMICONDUCTOR
Panasonic has a long history of developing world-class
consumer products. In the United States, Panasonic was
first to introduce an HDTV STB in 1998, and in 2003
Panasonic was first to introduce an integrated DTV with
both ATSC and OpenCable™ reception. There is no
question that Panasonic is a world leader in digital television. Panasonic Semiconductor’s DTV LSIs, proven in
Panasonic consumer products, are also widely used by
major DTV manufacturers around the world. We provide
strong support to all manufacturers.
Panasonic consumer products are built from the ground
up with only the best components and integrated circuits. Panasonic Semiconductor makes many of these
components and integrated circuits to ensure the highest quality in our consumer products. Now you can use
the same integrated circuits that made Panasonic a
world leader in DTV.
Integrated circuits are just one piece of the DTV puzzle.
To be successful in DTV, knowledge of the DTV marketplace and the required standards is key. Also critical are
a thorough understanding of how the complete system
works and how to implement hardware and software to
present a compelling proposition to the customer. Panasonic Semiconductor’s high-quality products and customer support are the answer to the DTV puzzle.
