Albalá Ingenieros | Manual DAT3000C01
The video input admits signals of 525 or 625 lines. When this signal is used as the
video reference input and the module is in Automatic Mode the converter
generates a sampling frequency of 48kHz. The other standard frequencies can be
generated by putting the module in Manual Mode and making the appropriate
selection.
The word-clock input admits a pulse train signal with TTL levels at a frequencies
that should correspond to one of the standard values. If the frequency of the TTL
signal is not a standard value then the DAT3000C01's oscillator will not be able to
sync.
The same connector is used for both the video reference input and the word-clock
reference input. Selection between the two input types is performed using the
module's internal program jumpers.
4.2.8.3. Operation in Manual Mode
This mode allows manual selection of any of the standard sampling frequencies
and of the reference input to be used. When a frequency other than the standard
ones listed is to be used, the operating mode should be set to variable speed.
