The Digilent Zmod ADC is an open-source hardware SYZYGY™ 1)compatible pod containing a dual-channel ADC and the associated front end. The Zmod ADC is intended to be used with any SYZYGY™ compatible carrier board having the required capabilities.

Figure 1. Zmod ADC top and bottom views.

The analog inputs can be connected to a circuit using SMA cables. Driven by the SYZYGY™ carrier, the Zmod ADC can acquire two simultaneous signals (1MΩ, ±25V, single-ended, 14-bit, 100MS/s, 70MHz+ bandwidth).

The Zmod ADC was designed to be a piece in a modular, HW and SW open-source ecosystem. Combined with a SYZYGY™ carrier, other SYZYGY™ compatible pods, Zmod ADC can be used for a variety of applications: data acquisition systems, closed loop controllers, scopes, etc.

Tutorials

These tutorials step through the process of creating a hardware platform that supports the Zmod ADC 1410. Prebuilt images for the Eclypse Z7 are available on the Digilent GitHub. The process of working with these prebuilt images is documented in Section 2 of the Zmod Base Library User Guide.
