comb filter, VBI data slicer and high performance scaler
SAA7114
16 PROGRAMMING START SET-UP
16.1
Decoder part
The given values force the following behaviour of the SAA7114 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.
