ADAQ8092-FMC HDL project

Overview

The EVAL-ADAQ8092 evaluates the ADAQ8092, a 14-bit, 105MSPS , high-speed dual-channel data acquisition uModule solution. This device uses the System-in-Package (SiP) that integrates three common signal processing and conditioning blocks.

This EVAL-ADAQ8092 board does not need an external power supply to operate and requires a very small jitter in the clock source. We recommend to use the DC1075B to improve the clock signal source. For full details on the ADAQ8092, see the ADAQ8092 data sheet, which must be consulted in conjunction with this user guide when using the EVAL-ADAQ8092.

CPU/Memory interconnects addresses

The addresses are dependent on the architecture of the FPGA, having an offset added to the base address from HDL (see more at HDL Architecture).

Building the HDL project

The design is built upon ADI’s generic HDL reference design framework. ADI distributes the bit/elf files of these projects as part of the ADI Kuiper Linux. If you want to build the sources, ADI makes them available on the HDL repository. To get the source you must clone the HDL repository, and then build the project as follows:

Linux/Cygwin/WSL

user@analog:~$ cd hdl/projects/adaq8092_fmc/zed
user@analog:~/hdl/projects/adaq8092_fmc/zed$ make

A more comprehensive build guide can be found in the Build an HDL project user guide.

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.
