1.6.2.14. Consider OCT features to save board space and verify that the required termination scheme is supported for all pin locations

Driver-impedance matching provides the I/O driver with controlled output impedance that closely matches the impedance of the transmission line to significantly reduce reflections. OCT maintains signal quality, saves board space, and reduces external component costs.
  • OCT RS are supported in the same I/O bank for different I/O standards if they use the same VCCIO supply voltage
  • Each I/O in an I/O bank can be independently configured to support OCT RS or programmable current strength
  • You cannot configure both OCT RS and programmable current strength or slew rate control for the same I/O buffer
