A.5.2. QSFP-DD Interface

The Agilex™ 7 FPGA F-Series (2 × F-Tiles) Development Kit board includes a connector and cages system for mounting a Double Density Quad Small Form-Factor Pluggable (QSFP-DD) module. The interface connects to eight 56 Gbps PAM4 capable F-Tile lanes of the Agilex™ 7 FPGA, supporting QSFP-DD modules, with capability of 400 Gbps aggregate bandwidth with power classifications up to 10 W.
