DATASHEETVP431

3U VPX Direct RF Processing Systemwith Xilinx Zynq Ultrascale+ RFSoC Gen3
The VP431 is a 3U VPX RF processing
system featuring the 3rd generation of thetransformational Xilinx® Zynq® Ultrascale+™
RF system-on-chip technology (RFSoC).
The ZU47DR device used on the VP431
includes eight integrated analog-to-digitalconverters sampling up to 5.0GSPS,
eight digital-to-analog converters up to10.0GSPS, a user programmable FPGA
fabric, and multi-core Zynq ARM® processing
subsystem. The VP431 is aligned withthe Sensor Open Systems Architecture™
(SOSA) technical standard and also supports
limited distribution options for enhancedperformance.
Reduce RF Signal Chain Complexity
RF systems with multiple channels sufferfrom a cost- and complexity challenge.
‘More channels’ means more expensive andlarge RF signal up/down conversion andsignal conditioning. As a solution, the VP431
enables direct RF sampling which can beprocessed in the digital domain, bringing
greater flexibility to the signal processing
chain. Additionally, close integration with RF
sampling devices removes the complexityof JESD204B/C high-speed serial interfaces
and reduces processing latency.
Maximize Input/Output Channel Density
The VP431 is one of the densest 3U VPX
analog FPGA processing boards available
with the ability to synchronize all 16 channels
and across multiple boards for even larger
system applications. Earlier generations
would have taken four times as many boards.

Heterogeneous processing capability
Many RF and signal processing systems
require both a streaming DSP with an
FPGA and a general-purpose processor fordecisions and control. In the past, theseprocessing requirements were handled byseparate modules. Now, with the VP431, itis possible to get both functions in a single
module by leveraging application and realtime processing ARM cores as part of theRFSoC technology.
Offload Data More Efficiently
The VP431 has VPX backplane interfacesaligned with the SOSA RF payload slot profile,
supporting 40 Gigabit Ethernet data plane,
PCIe Gen3 x4 expansion plane and Gigabit
Ethernet control plane connections to a hostcomputer or other payloads. With eight ADCs
sampling at rates up to 5GSPS, or higher
with the limited distribution device, and twobytes per sample, even these modern highspeed data connections are too slow for adirect transfer. To overcome this challenge,
the VP431 is available with an optional dual
channel 100 Gigabit Ethernet fiber optic
interface for transfers up to 25 GB/s.
The VP431 is available with two cooling
options, air or conduction, making it an ideal
COTS product for early designs and capable ofbeing deployed into operational assets. Whenpaired with Abaco’s extensive portfolio of
multi- architecture processing boards including
SBCs, GPGPUs, and fabric switches the stateof-the-art VP431 enables systems to be built
from leading edge, interoperable components.
