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
