Table 7. Unmasking SDIN2 Data from DAC5 Path
Due to the flexibility of the DAC5 path, it is possible to errantly unmask several data slots simultaneously.
If this occurs and DAC5 is not in Tracking Power Supply mode (see Section 4.6.5.1 Generating the Track-
ing Signal Inside the CS4234), only one data slot will be taken as the input into the DAC5 path. The se-
lection of this data slot is based upon the priority level of each of the slots which have been unmasked.
The priority structure is as follows:
1. Slot 1 of SDIN 1 receives 1
st
priority
2. Slot 2 of SDIN 1 receives 2
nd
priority
3. ...
4. Slot 16 of SDIN 1 receives 16
th
priority
5. Slot 1 of SDIN 2 receives 17
th
priority
6. ...
7. Slot 16 of SDIN 2 receives last priority.
