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
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
double-speed 54 MHz MPEG port; it is an input for “CCIR 656”style multiplexed Cb-Y-Cr
data; data is sampled on the rising and falling clock edge; data sampled on the 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)

2
C-bus register SRES = 0): 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. Sync reset input (I

C-bus register SRES = 1): a HIGH
impulse resets synchronization of the encoder (first field, first line).
