Figure 7-46, which shows the valid circular region in white and invalid corners in grey.

7.3.6.2 Channel Bonder

The channel bonder sits after the DUC blocks and is used to combine the outputs of the DUCs. A block diagram

for one DAC channel is shown in Figure 7-47. The DUC outputs can be scaled by 1 (0 dB), 0.5 (-6 dB) or

0.25 (-12 dB) as set by the DUC_GAIN registers to prevent saturation when summing the signals. The signals

are summed at full precision as determined by the settings of the DAC_SRC registers, and then saturation and

rounding occurs on the combined signal. When the DUC outputs are real, up to four DUCs are available to

be combined for each DAC. When the DUC outputs are complex, only two DUCs are available per DAC. The

channel bonder can combine any combination of the real or complex DUC outputs for each DAC.
