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.
