A 27-MHz digital-to-analog video processor

The authors describe a circuit intended for the restitution of a digital video signal into its analog red, green, and blue components. Sampling parameters according to CCIR recommendation 601 have been adopted for the digital interface. The circuit consists mainly of a complex digital processing part and three digital-to-analog converters. All of these functions have been implemented in a 38-mm/sup 2/ CMOS chip. The design goal was achieved by the development of an efficient 2- mu m CMOS technology dedicated to analog and digital applications.
