Flexible 4 Channel Analog In/Out
The RFX-8440 features variable gain down to -40dBm (input). The critical analog circuitry is designed to match the performance needs for a clean signal to/from the RFSoC's 14-bit interfaces. BittWare's high-performance analog PCB design spans three decades as a core strength.
Single-Chip Adaptable Platform
At the heart of RFX-8440 is the Zynq ZU43 RFSoC. This powerful single-chip adaptable radio platform provides up to 6GHz of direct RF sampling.
DIGITAL I/O
Getting digital data to/from the RFSoC is easy with the OCuLink 8× 25Gb/s interface. Connect to NVMe storage using BittWare's Data Recorder IP, other BittWare FPGA cards for further processing, a CPU host, or a custom interface card.
