Understanding Channel Placement Guidelines
f Refer to “Channel Placement for ×1 Variants” on page 7–47 for more information
about channel placement for ×1 and ×4 variants.For more information about
Cyclone V transceivers refer to the “PCIe Supported Configurations and Placement
Guides” section in the Transceiver Protocol Configurations in Cyclone V Devices.
