RF-DAC Converter Configuration - 2.6 English

Enable DAC

Select if the selected converter within the selected tile is enabled. Valid values are True and False.

Invert Q Output

When enabled, the Q output of the converter is inverted. This parameter is configurable only when I/Q output data is selected. A follow-on analog mixer must implement a subtraction, I x cos(f) - Q x sin(f) so the option to provide a -Q signal (negative quadrature) is provided so that the external mixer can perform the addition, I x cos(f) + (-Q)sin(f)

Inverse Sinc Filter

Select whether the inverse sinc filter is enabled or not. The parameter is only configurable when the converter is enabled. Valid values are TRUE and FALSE. This applies for both Nyquist zones, based on the Analog Settings > Nyquist Zone selection.

Enable TDD Real Time Ports (Gen 3 /DFE)

When enabled the tdd_mode port is added to the IP. This allows power savings to be made by powering down sections of the RF-DAC.
