DESCRIPTION
test pin; connected to digital ground for normal operation
test pin; connected to digital ground for normal operation
line-locked clock; this is the 27 MHz master clock for the encoder
digital ground 1
digital supply voltage 1
raster control 1 for video port; this pin receives/provides a VS/FS/FSEQ signal
raster control 2 for video port; this pin provides an HS pulse of programmable
length or receives an HS pulse
MPEG ports; inputs for
“CCIR 656”
style multiplexed C
B
-Y-C
R
data
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
