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