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.
