How to Enable on chip termination for 3.3V LVCMOS? - How to Enable on chip termination for 3.3V LVCMOS? I'm using Cyclone V - 5CEFA4F23C8 and would like to enable the OCT on some of the pins (Location PIN_P16 for example). I'm using 3.3-V LVCMOS I/O standard. I get this error message: "I/O standard 3.3-V LVCMOS on I/O pin xxxx cannot have termination logic option setting series 40 ohm without calibration" Am I missing something or is OCT really unavailable for this standard/pin?

To be clear, since the LVCMOS 3.3 isn't listed in either of the tables 5-29 or 5-30, it means that OTCs aren't available, right? Replies: Re: How to Enable on chip termination for 3.3V LVCMOS?
