Feedback Processing
The feedback path is input to RXC as a real ADC. This is captured in the capture buffer and sent to the DSP. In
cases where a higher-rate real ADC (>250 Msps) or a complex feedback path is desired, for better feedback
performance, one of the RX ADC inputs can be used for the feedback path, and one RX ADC input is used for
the RX path. Note: both RX downconverters can still be used for the RX path, or one can be used for feedback.
