2.3.2. GXT Channels
Set the following parameters:
- Set the VCCR_GXB and VCCT_GXB supply voltage for the transceiver parameter to 1_1V.
- Set the TX channel bonding mode parameter to Not Bonded.
- Set the datarate parameter between 17400 and 25800 (L-Tile, and 28300 (H-Tile).
- Set the number of channels between 1 and 16.
Because each ATX PLL's tx_serial_clk_gt can connect up to 2 GXT channels, you must instantiate one to eight ATX PLLs. Be aware of the GXT channel location and connect the appropriate ATX PLL’s tx_serial_clk_gt port to the Native PHY IP Core's tx_serial_clk port.
Refer to Using the ATX PLL for GXT Channels section for more details.
Refer to AN 778: Intel® Stratix® 10 Transceiver Usage for more information about transceiver channel placement guidelines for both L- and H-Tiles.
