Zmod DAC 1411: SYZYGY-compatible Dual-channel 14-bit Digital-to-Analog Converter Module

The Zmod DAC is one of Digilent's first SYZYGY-compliant expansion modules. The SYZYGY standard offers a much higher speed/bandwidth digital interface than Pmods, but at a much smaller and lower-cost form-factor than FMC, enabling the user to configure an FPGA development board with the right I/O for their application.

Driven by the SYZYGY carrier, the Zmod DAC can simultaneously generate two ±5V signals with 14 bits of resolution at a sample rate up to 100MS/s. The analog outputs can be connected to a circuit using SMA cables.

When coupled to a base board using 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 products. 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.
