5.1.1. Intel® Cyclone® 10 LP I/O Standards Voltage and Pin Support

Table 26.   Intel® Cyclone® 10 LP I/O Standards Voltage Levels and Pin Support
Note: The I/O standards that each pin type supports depends on the I/O standards that the pin's I/O bank supports. For example, only the I/O banks 1, 2, 4, and 6 support the LVDS (dedicated) I/O standard. To determine the pin's I/O bank locations for your device, check your device's pin out file.

21 You must enable the PCI clamp diode.
22 The 3.0 V PCI and PCI-X support is fully compatible for direct interface with 3.3 V PCI systems without additional components requirement. The outputs conforms to the VIH and VIL requirements of 3.3 V PCI and PCI-X inputs with sufficient noise margin.
23 Only for I/O banks 3, 4, 7, and 8.
24 Only for I/O banks 1, 2, 5, and 6.
25 Emulated LVDS, mini-LVDS, RSDS, and PPDS I/O standards requires external resistors.
26 Only for I/O banks 3, 4, 5, 6, 7, and 8.
