description: |
  Analog Devices Generic AXI DAC IP core for interfacing a DAC device
  with a high speed serial (JESD204B/C) or source synchronous parallel
  interface (LVDS/CMOS).
  Usually, some other interface type (i.e SPI) is used as a control
  interface for the actual DAC, while this IP core will interface
  to the data-lines of the DAC and handle the streaming of data from
  memory via DMA into the DAC.
