2.5.4. RZQ Pin Requirement

There is one RZQ pin per I/O sub-bank. The RZQ pins are dual-purpose pins, and can be used as GPIO if you do not use OCT calibration.

Adhere to the following guidelines if you use the RZQ pin:

  • To use the RZQ pins for OCT calibration, connect a precision resistor with a ±1% tolerance to the pins.
  • You cannot place the RZQ pin in an I/O lane with any input standard except LVCMOS, POD, or True Differential Signaling input buffer .
