3.13. GPIO Output may not meet the On-Chip Series Termination (Rs OCT) without Calibration Resistance Tolerance Specification or Current Strength Expectation

Description

The GPIO pull-up impedance may not meet the on-chip series termination (Rs OCT) without calibration resistance tolerance specification mentioned in the Intel® Arria® 10 device datasheet. While using the current strength selection, the GPIO output buffer may not meet expected current strength at VOH voltage level when driving HIGH.

Workaround

Enable the on-chip series termination (Rs OCT) with calibration in your design.
