The values shown in the table above are for standard power modes. In reduced power mode, the maximum data rate for Intel^® Arria^® 10 GX device channels (chip-to-chip) is 11.3 Gbps. As the GT transceiver channels are designed for peak performance, they do not have a reduced power mode of operation. To operate GX transceiver channels at designated data rates in standard and reduced power modes, apply the corresponding core and periphery power supplies. For more details, refer to the Intel^® Arria^® 10 Device Datasheet.
Intel^® Arria^® 10 and Intel^® Stratix^® 10 device transceivers can support data rates below 1.0 Gbps through over sampling.
For SX and GX device variants, the maximum transceiver data rates are specified for the fastest (–1) transceiver speed grade. Refer to the Device Datasheet for lower speed grade specifications.
For GT device variants, the maximum transceiver data rates are specified for (-1) transceiver speed grade. Refer to the Device Datasheet for the lower speed grade specifications.
Intel^® Stratix^® 10 device transceivers have both GX and GXT types of transceiver channels. For details, refer to the Intel^® Stratix^® 10 L-/H-Tile Transceiver PHY User Guide.
SR-IOV stands for Single-Root Input Output Virtualization.
Intel^® Arria^® 10 and Intel^® Stratix^® 10 device transceivers can support data rates below 1.0 Gbps through over sampling.
Backplane applications refer to the ones that require advanced equalization, such as decision feedback equalization (DFE) enabled to compensate for channel loss.
