Chapter 5: Evaluation Tool System Configuration using the GUI
Digital Down Converter Configurations
The GUI supports:
• Setting up complex mixer functionality and NCO frequency
• Setting the decimation rate on the decimation filters
• Selecting and configuring the decimation filter in the PL, if desired
• Configuring the quadrature modulator correction block
• Enabling and configuring dual band support
DAC Configuration
Like the ADC tiles, the DAC tiles contain four DACs. Unlike the ADC tiles, there is only one
configuration. The DAC tile contains the same clock generation (PLL) functionality as the
ADC tiles and a digital up converter (DUC) signal processing block.
The following features are supported in the GUI:
• DAC output current range (20 mA or 32 mA)
• DAC low noise mode
• DAC enhanced linearity mode
• DAC mix mode operation for second Nyquist zone operation
DAC Clock Configurations
The GUI supports:
• Selection of external or internal (PLL) sample clock options
• On-chip PLL configuration for internal sample clock generation
• Full access to configuring the on-chip PLLs using the software API
