A.5.2. QSFP-DD Interface

The Intel Agilex® 7 FPGA (two F-tiles) development 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 Intel Agilex® 7 FPGA, supporting QSFP-DD modules, with capability of 400 Gbps aggregate bandwidth with power classifications up to 10 W.
