Multi-channel Direct RF Sampling on a PCIe Card

The BittWare RFX-8440A data acquisition card features the third generation AMD Zynq® UltraScale+™ RFSoC. This data acquisition solution is capable of addressing a wide frequency spectrum – a critical need for applications such as 5G, LTE wireless, phased array RADAR and satellite communications. 

The RFX-8440A transfers digital data over OCuLink or QSFP at twice the rate of RFSoC cards that move data only over PCIe. The RFX-8440A does not require any power or signals from a PCIe slot. This allows deployment of a stand-alone RFX-8440A near an antenna where it converts analog data into a long-range optics, exchanging packets with a distant data center. Alternatively, it can be installed into a server PCI slot if needed. In this configuration it is wired to a dual 100 GbE NIC or to a separate FPGA card like our IA-440i. BittWare can deliver the RFX-8440A in a standard server or a chassis enclosure which provides power, cooling and interface to the RFX-8440A via RJ45.

4 Channel Analog In/Out

Tapping three decades of experience in designing sensor processing cards, BittWare’s analog front-end seamlessly crosses between analog and digital at up to S-Band rates.

Do More in the Digital Domain

At the center of the RFX-8440A is the latest generation single-chip RFSoC from Xilinx, the Zynq ZU43. This device is designed to bring together multi-channel data conversion and processing on a single chip.

"Now with complete coverage of sub-6GHz spectrum bands available as a readily-deployable PCIe card from BittWare, customers are able to gain a competitive advantage by accelerating the design and development of their next-gen wireless systems today."

Looking for L-Band?

Check out our RFX-8440L variant.

The RFX-8440 is available in two variants: the RFX-8440L and the RFX-8440A. RFX-8440L is a direct RF transceiver that can connect directly to an L-Band antenna to process signals. RFX-8440A is a data acquisition card that seamlessly crosses between analog and digital at up to S-Band rates.

4 Channel Analog In/Out

We’ve designed the critical analog circuitry to match the performance needs for a clean signal to/from the RFSoC’s 14-bit interfaces. Our heritage in high-performance analog PCB design spans three decades as a core strength for BittWare.

RFSoC chip

Powered by Third-Generation Xilinx Zynq UltraScale+ RFSoC

At the heart of the RFX-8440A card is the Zynq ZU43 RFSoC: a powerful single-chip adaptable radio platform providing up to 6 GHz of direct RF sampling. With a multi-element processing system: FPGA, real-time dual-core ARM and a second quad-core ARM, this RFSoC has what it takes to acquire, process and act on RF signals.

Digital I/O

Expansion Options With up to 200 Gb/s Bandwidth

200 Gbps of digital I/O is available on the FPGA side of the RFSoC. That is twice the bandwidth of RFSoC implementations that depend upon PCIe for data transfer.  This I/O is available through two QSFP28 cages, the most popular connector between chassis. Customers have implemented transports using Aurora, Ethernet MAC frames, and UDP.
