The QMC Gain features are built into the RF-ADC
tiles and offer a programmable gain between 0 and 2.0, with 16-bit output resolution.
Using this, the 12-bit RF-ADC output signal can be
placed to give a flexible dynamic range through the digital datapath. The application
moment of the gain value in the QMC block can be controlled by the adcXY_pl_event signal. This signal is controlled directly
from the user design in the PL and should be delayed to account for the latency required
by the external VGA adjustment and RF-ADC conversion.
When using this option, the sticky threshold outputs can be auto-cleared when the gain
is applied.
