7.4.1.3. On-Chip Termination Recommendations for Cyclone® 10 Devices
- Output mode (drive strength) for Address/Command/Clock and Data Signals: Depending upon the I/O standard that you have selected, you would have a range of selections expressed in terms of ohms or milliamps. A value of 34 to 40 ohms or 12 mA is a good starting point for output mode drive strength.
- Input mode (parallel termination) for Data and Data Strobe signals: A value of 40 or 60 ohms is a good starting point for FPGA side input termination.
