How do I set-up the DLL for the DAC5682Z (or the DAC5681Z or DAC5681)?
The best way to set up this is to use a cookbook approach:
First you need to determine the DCLK frequency.
With the DCLK frequency you need to check the DLL Operating Frequency table from the "Electrical Characteristics" section of the datasheet.
The table maps the DLL frequency to a Register 0x0A configuration. Register 0x0A has all the DLL settings.
