2.4.3.2. RS OCT in Intel® MAX® 10 Devices

Table 13.  Selectable I/O Standards for RS OCT

This table lists the output termination settings for RS OCT with and without calibration on different I/O standards.

  • RS OCT with calibration—supported only on the right side I/O banks of the Intel® MAX® 10 16, 25, 40, and 50 devices.
  • RS OCT without calibration—supported on all I/O banks of all Intel® MAX® 10 devices.
