AD719X-ASDZ HDL project#

Overview#

The AD719x family uses a low noise, higher speed, high precision ADC. They can be used in a wide range of applications where the input signals can vary from the milli-volt to volt level. The parts also operate with a wide range of output data rates while still maintaining excellent noise performance over the complete rate of output data ranges.

Building the HDL project#

The design is built upon ADI’s generic HDL reference design framework. ADI does not distribute the bit/elf files of these projects so they must be built from the sources available here. To get the source you must clone the HDL repository.

Then go to the project location(projects/ad719x/coraz7s) and run the make command by typing in your command prompt:

Linux/Cygwin/WSL

user@analog:~$ cd hdl/projects/ad719x_asdz/coraz7s
user@analog:~/hdl/projects/ad719x_asdz/coraz7s$ make

Check this guide on how to prepare your SD card with the proper boot files. A more comprehensive build guide can be found in the Build a HDL project user guide.

Software considerations#

The SPI communication is changed because of hardware modifications, so the connection looks like this:

Support#

Analog Devices, Inc. will provide limited online support for anyone using the reference design with ADI components via the EngineerZone FPGA reference designs forum.

For questions regarding the ADI Linux device drivers, device trees, etc. from our Linux GitHub repository, the team will offer support on the EngineerZone Linux software drivers forum.

For questions concerning the ADI No-OS drivers, from our No-OS GitHub repository, the team will offer support on the EngineerZone microcontroller No-OS drivers forum.

It should be noted, that the older the tools’ versions and release branches are, the lower the chances to receive support from ADI engineers.
