12. Programming start setup of digital video decoder part
12.1 Decoder part
The given values force the following behavior of the SAA7108AE; SAA7109AE decoder
part:
• The analog input AI11 expects an NTSC M, PAL B, D, G, H and I or SECAM signal in
CVBS format; analog anti-alias filter and AGC active
• Automatic field detection enabled
• Standard ITU 656 output format enabled on expansion (X) port
• Contrast, brightness and saturation control in accordance with ITU standards
• Adaptive comb filter for luminance and chrominance activated
• Pins LLC, LLC2, XTOUTd, RTS0, RTS1 and RTCO are set to 3-state
