Product data sheet
Scaler input format and configuration source selection
Only if XRQT[83h[2]] = 1: scaler input source reacts on SAA7118
request
Scaler input source is a continuous data stream, which cannot be
interrupted (must be logic 1, if SAA7118 decoder part is source of
scaler or XRQT[83h[2]] = 0)
Scaler input source is data from decoder, data type is provided
according to
Scaler input source is Y-C
Scaler input source is raw digital CVBS from selected analog
channel, for backward compatibility only, further use is not
recommended
Scaler input source is raw digital CVBS (or 16-bit Y + C
16-bit outputs are active) from X port
SAV/EAV code bits D6 and D5 (F and V) may change between
SAV and EAV
SAV/EAV code bits D6 and D5 (F and V) are synchronized to
scalers output line start
SAV/EAV code bit D5 (V) and V gate on pin IGPV as generated by
the internal processing; see
SAV/EAV code bit D5 (V) and V gate are inverted
Scaler input format and configuration format control
Input is Y-C
Input is Y-C
Chroma is provided every line, default
Chroma is provided every 2nd line
Chroma is provided every 3rd line
Chroma is provided every 4th line
X port input reference signal definitions
Rising edge of XRV input and decoder V123 is vertical reference
Falling edge of XRV input and decoder V123 is vertical reference
XRV is a V-sync or V gate signal
X = don’t care.
X = don’t care.
FSC2 and FSC1 only to be used, if X port input source does not provide chroma information for every input line. X port input stream
must contain dummy chroma bytes.
