6.5 Sample Clock Configuration 0/1
The register defines the source for the operating respectively sampling clock. This setting is applied due to
physical restrictions (see chapter “Clock Distribution”) on a group of ADCs (0-3 and 4-7) where the below
structure is the same for both groups.
Choosing a clock source must be done considering the ADCs specification to avoid a physical damage.
