16 PROGRAMMING START SET-UP
16.1 Decoder part
The given values force the following behaviour of the SAA7118 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, XTOUT, RTS0, RTS1 and RTCO are set to 3-state.
