Digital Outputs 3.3.9
Digital outputs characteristics can be configured:
 Clock polarity: normal or inverted.
 Data (I/Q) polarity: normal or inverted.
 Data swap: Normal I & Q, I inverted & Q, I & Q inverted, I inverted & Q inverted
+ Swap: Q & I, Q inverted & I, Q & I inverted, Q inverted & I inverted
 Output mode: Normal or split (separate I & Q output) or I/Q merged or CADU output (refer to
the Hardware Description chapter)
