4.5. PCI Express Gen3 Bank Usage Restrictions

Any transceiver channels that share a bank with active PCI Express interfaces that are Gen3 capable have the following restrictions. This includes both Hard IP and Soft IP implementations:

  • When VCCR_GXB and VCCT_GXB are set to 1.03 V or 1.12 V, the maximum data rate supported for the non-PCIe channels in those banks is 12.5 Gbps for chip-to-chip applications. These channels cannot be used to drive backplanes or for GT rates.

PCI Express interfaces that are only Gen1 or Gen2 capable are not affected.

Status

Affects all Intel® Arria® 10 ES and production devices. No fix is planned.
