Overview

Description#

The 2x QSFP28 FMC is an add-on expansion board (FPGA Mezzanine Card) for FPGA and SoC-based development boards. It has two QSFP28 module slots, allowing the connection of up to two QSFP28, QSFP+ or QSFP modules to the carrier development board. Each QSFP28 port provides four lanes of up to 25 Gbps each, for an aggregate bandwidth of up to 100 Gbps per port. The mezzanine card features a jitter-attenuating clock multiplier, supporting Synchronous Ethernet applications, and uses level translators to support a wide range of FPGA I/O voltages from 1.2VDC to 3.3VDC.
