18.104.22.168. 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. The impedance of the I/O buffer is continuously altered until the target impedance is achieved during OCT calibration. The targeted impedance is achieved when the impedance of I/O buffer reaches a predetermined ratio to the reference resistance.
|Output||RS OCT with calibration|
|RS OCT without calibration|
|Input||RT OCT with calibration|
