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.
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.

Analog Front End Options
The analog front end provides a direct connection with baluns supporting up to 4 GHz. The difference between the 3 and 4 GHz options is the balun transformer. The 3 GHz transformer offers slightly better, low frequency performance for customers who do not need the full 4 GHz top end.

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.
- Four ADC channels, 14-bit, 5.0GSPS
- Four DAC channels, 14-bit, 10.0GSPS
- External reference and triggers
- Programmable clocks

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.
- Industry's only adaptable single-chip radio platform
- Move RF design to the digital domain
- Programmable logic for diverse requirements and emerging standards
- Lower power by eliminating JESD204 interfaces
- Reduce PCB area vs. discrete solutions
- Future-proof comprehensive solution
- Full sub-6GHz support with extended millimeter wave interfacing and multi-band support

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 on PCIe for data transfer. This I/O is available on a single, 8x OCuLink port, a popular connector used inside a chassis. We also offer an add-on that provides the same signals through two QSFP28 cages, the most popular connector between chassis. Customers have implemented transports using Aurora, Ethernet MAC frames, and UDP.
Getting digital data to/from the RFSoC is easy with the OCuLink 8× 25 Gb/s interface. You can connect to NVMe storage (using our Data Recorder IP), other BittWare FPGA cards for further processing, a CPU host, or let us design a custom interface card for your need.
- OCuLink Expansion Port, 8× 25 Gb/s
- Optional configuration for 2× front panel QSFP28s (uses internal OCuLink cable)
- Xilinx Hard IP support for dual 100GbE and PCIe Gen4 (PCIe requires 3rd party adapter)
- Custom lightweight protocols to connect to other FPGA cards
- Customized Molex connectors/cables as required for your application
- Additional I/O ports include RJ45 (1GbE), USB 3.0 and Mini DisplayPort
