• Video input for ITU-R BT.656 format
• Video scaling and aspect conversion
• Unified Memory Architecture. Main memory is DDR333 or DDR400 SDRAM with a capacity from 128 Mbits to 2 Gbits
• NAND flash memory interface (8- and 16-bit) that supports ECC calculation and error detection
• 32-bit RISC CPU delivers 200 MIPS and makes efficient use of system resources by using variable-length instructions
• Transport decoder can demultiplex one stream from up to 3 sources; 48 PID filters, 40 section filters, supports partial TS output
• Conditional access support: DES-ECB for Plug-and-Play/OpenCable™, Multi2 descrambler for Japanese satellite, and DVB common descrambler for Europe
• Available 2-channel audio digital input with synchronization to video signal output
• Video and audio decoding for MPEG1, MPEG2, AAC, and Dolby® Digital (AC-3)

Application Scenarios

The MN2WS0175B is used in digital TV and set-top box applications in the United States, Japan, and Europe. It can be used to design a low-cost yet highly featured product, thanks to its built-in CableCARD™ interface.

Comparison

• The built-in CableCARD™ interface reduces system cost
• Complete hardware and software design package dramatically reduces time-to-market
• Optional software modules support a variety of DTV functions including the CableCARD™ stack for Plug-and-Play/OpenCable™, DTV closed captioning, and channel map database
• Development support and access to Panasonic Semiconductor’s “customer room.” Available source feeds for ATSC, NTSC, and both Motorola and SA headends. Also available are HPNX™ verification tools required to test Plug-and-Play/OpenCable™ compliance and Sarnoff bitstreams to test MPEG and PSIP compliance
• Reference design comes with schematics and Gerber files, bill of materials (BOM), datasheets, software stacks, and applications support.
