• The given values force the following behaviour of the SAA7111A:
– The analog input AI11 expects a signal in CVBS format; analog anti-alias filter active
– Automatic field detection
– YUV 4 : 2 : 2 16-bit output format enabled
– Outputs HS, HREF, VREF and VS active
– Contrast, brightness and saturation control in accordance with CCIR standards
– Chrominance processing with nominal bandwidth (800 kHz).
