A prototype mixed signal video decoder will be developed as an integrated circuit. This will be achieved in two phases. Phase 1 will produce the sigma delta modulator and phase 2 will prove it in the mixed signal application for which it was intended. The resultant design will perform the mixed-signal processing as demanded by customer inputs to decode NTSC/PAL signals to 60dB SNR in one instance and recover 256 QAM modulated  or similar digital transmission format in another.

 

This project will prove the application of sigma-delta signal processing as efficient in cost/size and power versus an existing implementation in high accuracy video signal conversion.

 

Analog Devices will sell the product competitively in a variety of video markets. NMRC and PEI will apply the results in education programmes and courses of a commercial nature in accordance with IC & D requirements and will develop further areas of research with the commercial partner.

 

Mixed mode analog design methodologies will be employed to verify the design before manufacture. The application of the work to other market areas means that the results will be of benefit to mixed-signal designers from a cross-section of market areas that require high-speed, high accuracy low voltage designs.
