I/O Standard Specifications
I/O Standard Specifications
Tables in this section list the input voltage (VIH and VIL), output voltage (VOH and VOL), and current drive characteristics (IOH and IOL) for various
I/O standards supported by Arria 10 devices.
For minimum voltage values, use the minimum VCCIO values. For maximum voltage values, use the maximum VCCIO values.
You must perform timing closure analysis to determine the maximum achievable frequency for general purpose I/O standards.

To meet the IOL and IOH specifications, you must set the current strength settings accordingly. For example, to meet the 3.0-V LVTTL specification
(2 mA), you should set the current strength settings to 2 mA. Setting at lower current strength may not meet the IOL and IOH specifications in the
datasheet.
