184.108.40.206. Single-Ended I/O Standard OCT Termination
The OCT calibration circuit uses the impedance of the external resistor that is connected to the RZQ pin as reference. During calibration, the circuit continuously alters the impedance of the I/O buffer until the impedance reaches a predetermined ratio to the reference resistance.
The OCT with calibration feature is not supported in GPIO mode.
|Output||RS OCT with calibration|
