TYPE
reserved pin; do not connect
test pin; connected to digital ground for normal operation
test pin; connected to digital ground for normal operation
line-locked clock input; this is the 27 MHz master clock
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
double-speed 54 MHz MPEG port; it is an input for “ITU-R BT.656” style multiplexed
C
rising edge is then sent to the encoding part of the device; data sampled on the falling
edge is sent to the RGB part of the device (or vice versa, depending on programming)
real-time control input; if the LLC1 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
