5.5.3.1. Programmable Current Strength
You can use the programmable current strength to mitigate the effects of high signal attenuation that is caused by a long transmission line or a legacy backplane.
Note:
To use programmable current strength, you must specify the current strength assignment in the Intel® Quartus® Prime software. Without explicit assignments, the Intel® Quartus® Prime software uses these predefined default values:
- All HSTL and SSTL Class I, and all non-voltage-referenced I/O standards—50 Ω RS OCT without calibration
- All HSTL and SSTL Class II I/O standards—25 Ω RS OCT without calibration
- POD12 I/O standard—34 Ω RS OCT without calibration
