Digilent Zmod Digitizer 1430-123: 2-channel 14-bit digitizer module

The Digilent Zmod Digitizer is a SYZYGY compatible module containing a dual-channel ADC and the associated front end. The Zmod Digitizer is intended to be used with any SYZYGY compatible carrier board having the required capabilities.

When coupled to a base board using the SYZYGY expansion, like the Eclypse Z7 or Genesys ZU, the combination will serve as a powerful prototyping platform for instrumentation, high-speed control, and SDR. By utilizing these expansion capabilities, users can spend more time on the analytical and system-level aspects of the solution rather than having to focus on the component-level interactions of the devices.

The Zmod Digitizer module is a variant of the similar Zmod Scope module but optimized for RF signal acquisition and frequency-domain analysis. The simpler DC-coupled input and 60 MHz anti-aliasing input filter improves immunity to stray RF radiation and the versatile and very low-jitter on-board clock generator enables acquisition at key rates, including 122.8 MHz often used in SDR applications.
