About the Timing Mode
There are two versions of the ADC-8032A available. The standard ADC-8032A can be timed within
one line in 37ns increments. The ADC-8032A-S with the frame synchronizer can be timed within one
video frame in 37ns increments. The fine phase potentiometer (RV1) is provided for sub-pixel
adjustment.
The presence of a frame synchronizer means that the Frame Delay and Frame Sync modes are
available. Without the frame synchronizer, the Line Delay and Line Sync modes are available.
Looking at it another way, the S version provides a full frame of memory, whereas the non-S version
provides a few lines of memory. This means that the non-S version provides enough timing flexibility
to meet a wide variety of applications. It also means that these cards can be upgraded in the field for
full frame synchronizing capabilities. The following information provides detailed explanations of
when to use each mode, as well as an analysis of the advantages each mode has to offer.
Line Delay (ADC-8032A & ADC-8032A-S)
Line Delay mode uses the input signal to generate the output timing. In other words, it provides a
constant delay between the input and the output. The external reference is not used in any way. This
is useful in applications where a constant delay through the card is required.
The delay through the card has a minimum value, as described in Chapter 7, “Specifications”. Output
timing can be adjusted from this minimum delay up to an additional two lines in sub-pixel increments.
