Opal Kelly XEM8320-AU25P — Artix UltraScale+ FPGA Module with SYZYGY and SFP+ Expansion

Specifications

Overview

The XEM8320-AU25P is Opal Kelly's Artix UltraScale+ integration module. It carries an XCAU25P-2FFVB676E FPGA with 1 GiB of DDR4 and a 256 Mib serial boot device, and exposes its I/O through four SYZYGY Standard ports plus two SYZYGY TXR4 transceiver ports and two SFP+ cages — enough to attach high-speed ADCs and DACs, cameras, SFP+ optical links and Pmod breakouts to a single 170 x 97 mm board.

Host communication runs over a USB Type-C port driven by the FrontPanel SDK, which sustains 350+ MB/s with no custom driver work. Three low-jitter clock oscillators are provided on board so mixed-rate acquisition and optical links can each get a suitable reference.

Key Benefits

XCAU25P with 1 GiB DDR4 handles deep capture buffers and image frames. Four SYZYGY Standard plus two TXR4 ports scale from simple Pmod-class peripherals to multi-gigabit transceiver links. Two SFP+ cages make optical and copper networking experiments a cable-away task. FrontPanel SDK at 350+ MB/s shortens host-side development to a library call.

Applications

Modular instrumentation, streaming data acquisition, machine-vision and imaging prototypes, optical and Ethernet transport experiments, and laboratory FPGA development where I/O variety matters more than raw fabric size.
