5.4. Channel Layout and PLL Usage

The following figures show the channel layout and PLL usage for Gen1, Gen2 and Gen3, x1, x2, x4, x8 and x16 variants of the Intel L-/H-Tile Avalon-MM for PCI Express IP core. Note that the missing variant Gen3 x16 is supported by another IP core (the Intel L-/H-Tile Avalon-MM+ for PCI Express IP core). For more details on the Avalon® -MM+ IP core, refer to https://www.intel.com/content/www/us/en/programmable/documentation/sox1520633403002.html.

The channel layout is the same for the Avalon® -ST and Avalon® -MM interfaces to the Application Layer.

Note: All of the PCIe hard IP instances in Stratix® 10 devices are x16. Channels 8-15 are available for other protocols when fewer than 16 channels are used. Refer to Channel Availability for more information.
