GENERAL DESCRIPTION
The SAA7199B encodes digital baseband colour/video
data into analog Y, C and CVBS signals (S-video
included). Pixel clock and data are line-locked to the
horizontal scanning frequency of the video signal.
The circuit can be used in a square pixel or in a consumer
TV application. Flexibility is provided by programming
facilities via MPU-bus (parallel) or I
