Digilent Zmod SDR: SYZYGY-compatible Analog-to-Digital Converter Module

The Digilent Zmod SDR is a digitizer designed for software-defined radio and RF applications. It is a SYZYGY- 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.
