Multi-channel Direct RF Sampling on a Single Chip

With flexibility to serve applications like 5G, RADAR, test & measurement and satellite communications, BittWare’s new RFX-8440 features the latest third-generation RFSoC UltraScale+ Zynq device from Xilinx.

4 Channel Analog In/Out

Tapping three decades of experience in designing sensor processing cards, BittWare’s analog front-end features variable gain in/out down to -40 dBm (input) and optimized for L Band. Other analog configurations available.

Do More in the Digital Domain

At the center of the new RFX-8440 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."
David Brubaker
Senior product line manager, Wired and Wireless Group, Xilinx

RFX-8440 PCIe card, shown in dual-width passive configuration. Dual-width active and single-width passive options are available. Card is designed to work in a host system or standalone.

Flexible 4 Channel Analog In/Out

With features like variable gain down to -40 dBm (input), 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
  • Variable gain input: -40 to 0 dBm
  • Variable gain output: -40 to 0 dBm
  • External reference and triggers
  • Programmable clocks

Powered by Third-Generation Xilinx Zynq UltraScale+ RFSoC

At the heart of RFX-8440 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
