Enable Real Time Ports
Enables the RF-DAC Fast Shutdown and pl_event ports.
Enable Real Time NCO Ports
The frequency and phase of the mixer NCO in the DUC can be modified in real time. Selecting this option enables the real time NCO interface for the RF-DAC. The operation of this interface is described in NCO Frequency Hopping.
Output Current
Select between 20 mA and 32 mA RF-DAC output current. In 20 mA mode, DAC_AVTT is equal to 2.5V. In 32 mA mode, DAC_AVTT is equal to 3.0V.
Variable Output Current Mode (Gen 3/DFE)
When Variable Output Current mode is off the output current is set by the Output Current option. In 20 mA mode, DAC_AVTT is equal to 2.5V. In 32 mA mode, DAC_AVTT is equal to 3.0V. When Variable Output Mode is enabled the output current can be set on a per-tile basis by the Variable Output Current field in the RF-DAC tab. DAC_AVTT is set to 3.0V.
Enable Real Time Variable Output Power Ports (Gen 3/DFE)
If this option is selected a real-time VOP signal interface is added for each enabled RF-DAC. This enables the update of the output power in real time.
Variable Fabric Width (Gen 1/Gen 2)
This option should be enabled if a Gen 1 or Gen 2 design is configured to use multi-tile sync and it is intended to vary the fabric width via the driver.
