Variations on RS-343A
Various other video output configurations can be implemented
by the ADV7152, including RS-170. Values of R
SET
for particu-
lar output video formats/levels are calculated by using the equa-
tions for R
SET
given in the “Pin Configuration” section. T he
table shows calculated values of R
SET
for some of the most com-
mon variants on the RS-343A standard. T he associated wave-
forms are shown in the diagrams.

I
PLL
Synchronization Output Control
T his output synchronization signal is used in applications where
it is necessary to synchronize multiple palette devices (ADV7150
+ ADV7151) to subpixel resolution. Each devices I
PLL
output
signal is in phase with its analog RGB output signal. If multiple
devices have differing output delays, the time difference can be
derived from the I
PLL
signals. T his time difference is then used
to phase shift the
CLOCK
inputs on one or other of the devices
inputs.
T he I
PLL
signal is internally triggered by either the falling edge
of
SYNC
or
BLANK
as determined by CR21 of Command
Register 2.
