NORWOOD, Mass. (PRWEB) January 21, 2008
The ADV7802 is the industry's only true 12-bit-resolution decoder with 4:4:4 sampling throughout the processing pipeline, including support for RGB SCART inputs, to provide designers with a higher level of system performance compared to existing 8-bit industry offerings using 4:2:2 sampling schemes. The addition of an on-chip interface with support for SDR (single data-rate) DRAM reduces overall system cost while support for DDR (double data-rate) DRAM enables simultaneous 12-bit 3D comb (NTSC or PAL), digital noise reduction (DNR) and time base correction (TBC), providing designers with a complete solution for decoding standard-definition (SD) video for noisy off-air broadcast signals or poor-quality VCR tape recordings with unstable timing.
The ADV7802's multi-format conversion capability allows designers to easily convert analog video signals to create the vivid images, deeper colors and enhanced digital imaging features that consumers have come to expect in their video-processing and digital-TV applications. For TV chassis designs targeted to multiple end markets, the ADV7802 automatically detects and performs 3D comb filtering for a wide range of video standards in all regions, including all variants of NTSC and PAL. Advanced SECAM decoding is also supported. In addition, support for detecting and decoding weak terrestrial TV broadcast signals has been improved to ensure the best possible picture, even under remote reception conditions.
Leveraging ADI's superior analog-to-digital (ADC) converter technology and advanced adaptive Y/C separation algorithms, the highly integrated single-chip solution provides high-end video performance with its 3-tap, zero field latency 3D comb filter which operates on the full PAL field sequence. The ADV7802's 3D adaptive comb filter produces sharper, more accurate color reproduction, while the decoder's enhanced 12-bit YCbCr or RGB output capability (with interlaced or conversion to progressive scan timing) enhances a system's HDMI(TM) (High Definition Multimedia Interface(TM)) Deep Color processing capabilities - even for analog input sources.
Availability and Pricing
The ADV7802 12-bit 3D comb video decoder is now shipping in production quantities and is available in a 176-pin TQFP (thin quad flatpack) package.
