The Digilent Zmod SDR is a digitizer designed for software-defined radio and RF applications. It is a SYZYGY™ 1)-compatible pod containing a dual-channel ADC and the associated front end. The Zmod SDR is intended to be used with any SYZYGY™ compatible carrier board. It features a wide input bandwidth, allowing for under-sampling applications - capturing signals with frequencies much higher than the baseline 122.88 MS/s sample rate's associated Nyquist frequency. An on-board low-jitter clock generator and low-noise design provide the precision necessary to capture fast radio signals. When paired with an Eclypse Z7 host board, the Zmod is supported in GNU Radio, providing a convenient and familiar interface for SDR experts and researchers.

    • The vivado-library IP repository contains the ZmodSDRController IP core, which can be used to interface with the Zmod. It handles the initial configuration of the Zmod and provides a standard AXI4-stream interface for digitized data. under review
  • Provide location constraints?
    • The dpmutil repository on Github contains software sources that can be used with a suitable baremetal software project to extract calibration coefficients from SYZYGY DNA. to be updated

Note: No Vivado projects built around the Zmod SDR are provided by Digilent.


Compatible Digilent Host Boards

Note: The ZmodSDRController IP is only supported on 7-series FPGAs.
