High-speed real-time data acquisition and processing form the fundamental part of all innovative design developments. Taking this into account, iWave Systems has successfully developed and demonstrated a high-speed analog data acquisition and processing system over the JESD204B serial interface on our Zynq® UltraScale+™MPSoC Development Platform. The JESD204B interface offers seamless connectivity between the AD-FMCDAQ2-EBZ data converters and Zynq Ultrascale+ MPSoC platform, accelerating the development of analog-based designs.
The Zynq Ultrascale+ MPSoC Development Platform :
iWave’s Zynq Ultrascale+ SoC Development Kit comprises of Xilinx Zynq Ultrascale+ MPSoC SOM and high-performance carrier card. The SOM is equipped with 64-bit 4GB DDR4 RAM with ECC for PS & 16-bit 1GB for PL. The carrier board supports a rich set of features like FMC (HPC) Connectors, SATA, SFP+, Display Port, USB-Type-C and PCIe x4 connector.
Xilinx Zynq Ultrascale+ SoC suites aptly for the Data Acquisition and Processing Application over JESD204B due to the following key attributes:
The JES204B interface offers the following key benefits in embedded systems:
The combination of JESD204B compliant AD-FMCDAQ2-EBZ module and Zynq® UltraScale+™ development board allows quick prototyping and development of FPGA based design solutions that require high-speed data acquisition. Advance use cases include Test and measurement equipment, Radar/Lidar systems, 4G/5G solutions, General-purpose software-defined radios (SDR), Motor control, High-speed data transfer, Ultra-wideband satellite receivers and more.

External raw analog data capture from ADC and sent to FPGA-SoC for processing and storing, processed data is sent back to the external world in analog form over DAC.
Analog data in the form of a sine wave is provided by the signal generator to the ADC, FPGA captures the digitized data from ADC over JESD204B interface and is sent to SoC for further processing and also optional logging onto on-board mounted M.2 SATA memory as well as a stream over Ethernet interface for further data analysis. On-board 4Gb DDR4 is used for buffering and other data manipulation by the SoC.
The ADC captured data is sent to DAC via JESD204B interface and analog output is displayed on the Mixed Domain Oscilloscope in frequency & time domain.
Data generator internal to FPGA-SoC generates the known data pattern, which is sent over DAC to the external world and the analog data is looped back and received into the FPGA-SoC through ADC and post-processing of the captured digitized data and optional storing.
Data Pattern Generator pumps the data stored in the internal RAM to the DAC over the JESD204B interface, AD9144 DAC will do the conversion. The analog output from the DAC is looped back to the ADC using SMA cables. FPGA captures the digitized data from ADC over the JESD204B interface and sent to SoC for further processing. On-board 4Gb DDR4 is used for buffering and processed data will be stored in on-board mounted M.2 SATA memory as well as a stream over Ethernet interface for further data analysis and verification using the GNU plot application at the Host PC.
DAC output Details:
A 25MHz Sine wave digital pattern has been sent to DAC, which will have 40 samples per each crest and trough.ADC captured data plotted on the GNU plot application verifies the number of the samples per each crest and trough and ADC’s input voltage range 1.7Vp-p also can be seen at the GNU plot’s Y2 axis.
