5.5. LVDS SERDES
When migrating from AGI 022/027 to AGM 032/039, ensure that the VCCIO_PIO supply changes accordingly in the board design. The True Differential Signaling I/O standard used in AGI 022/027 requires 1.5V VCCIO_PIO supply but the same I/O standard in AGM 032/039 requires 1.3V VCCIO_PIO supply.
For example, when migrating LVDS SERDES channels from bank 3A in AGI 022/027 to bank 3A in AGM 032/039, ensure that the VCCIO_PIO for bank 3A in AGM 032/039 is supplied by 1.3V and not 1.5V.

Note: Refer to the Agilex™ 7 Pin Connection Guidelines to manage the unused power, I/O, and VREF pins.
Note: Ensure that VCCIO_PIO and VREF of the target migration bank are compatible before performing migration.
