RCV1
35
Raster Control 1 for video port. This pin receives/provides a VS/FS/FSEQ signal.
RCV2
36
Raster Control 2 for video port. This pin provides an HS pulse of programmable length or
receives an HS pulse.
RTCI
37
Real Time Control Input. If the LLC clock is provided by an
SAA7111 or SAA7151B, RTCI
should be connected to the RTCO pin of the respective decoder to improve the signal quality.
