Single-Ended SSTL, HSTL, and HSUL I/O Standards Signal Specifications
Table 21: Single-Ended SSTL, HSTL, and HSUL I/O Standards Signal Specifications for MAX 10 Devices—Preliminary
To meet the IOL and IOH specifications, you must set the current strength settings accordingly. For example, to meet the SSTL-15 Class I specification (8
mA), you should set the current strength settings to 8 mA. Setting at lower current strength may not meet the IOL and IOH specifications in the datasheet.
