AD9213-EVB HDL project

Overview

The AD9213-EVB reference design is a processor based (e.g. Microblaze) embedded system.

The design implements a high-speed receive chain using JESD204B.

The receive chain transports the captured samples from ADC to the system memory (DDR). Before transferring the data to DDR the samples are stored in a buffer implemented on block rams from the FPGA fabric (util_adcfifo).

All cores from the receive chain are programmable through an AXI-Lite interface.

Block design

The data path and clock domains are depicted in the below diagrams:

The Rx links (ADC Path) operate with the following parameters:

• Rx parameters: L=16, M=1, F=2, S=16, NP=16, N=16

• Sample Rate: 10 GSPS

• Dual link: No

• RX_DEVICE_CLK: 312.25 MHz (Lane Rate/40)

• REF_CLK: 625 MHz (Lane Rate/20)

• JESD204B Lane Rate: 12.5 Gbps

• QPLL0

\[Lane Rate = Sample Rate*\frac{M}{L}*N'* \frac{10}{8}\]

Clock scheme

The clock sources depend on the carrier that is used:

VCU118

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.

Then go to the projects/ad9213_evb location and run the “make” command by typing in your command prompt.

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.
