The First Expansion to the Zmod Family
In early 2020, Digilent released the Eclypse Z7 development board, which provided two SYZYGY-compatible connection ports. SYZYGY is a relatively new interface standard that provides more performance than Pmod while being more space-efficient and cost-effective than FMC. Alongside the release of the Eclypse Z7, Digilent created two “Zmods”, or SYZYGY- compatible modules: the Zmod ADC 1410 and Zmod DAC 1411, which brought high-speed I/O to the Eclypse platform.
In 2021, we are excited to be substantially expanding our Zmod offerings. The first addition to the Zmod family will include six new modules. We’re continuing to focus on high-speed I/O and rolling out additional Zmod ADCs, with analog-to-digital converters of varying performance. The new Zmod ADCs will offer resolution at 10-, 12-, and 14-bit with sampling rates ranging from 10MS/s up to 125MS/s. With this degree of variance, we think they’ll be helpful for engineers and researchers from telecommunications to prototyping to embedded OEM. Peep this table for the specifications of each individual module:
