AD722
Synchronous vs. Asynchronous Operation
The source of RGB video and synchronization used as an input
to the AD722 in some systems is derived from the same clock
signal as used for the AD722 subcarrier input (FIN). These
systems are said to be operating synchronously. In systems
where two different clock sources are used for these signals, the
operation is called asynchronous.
The AD722 supports both synchronous and asynchronous op-
eration, but some minor differences might be noticed between
them. These can be caused by some details of the internal
circuitry of the AD722.
There is an attempt to process all of the video and synchroniza-
tion signals totally asynchronous with respect to the subcarrier
signal. This was achieved everywhere except for the sampled de-
lay line used in the luminance channel to time align the lumi-
nance and chrominance. This delay line uses a signal at twice
the subcarrier frequency as its clock.
The phasing between the delay line clock and the luminance sig-
nal (with inserted composite sync) will be constant during syn-
chronous operation, while the phasing will demonstrate a
periodic variation during asynchronous operation. The jitter of
the asynchronous video output will be slightly greater due to
these periodic phase variations.
