5.7
A Functional representation of the output buffer is shown as below. Output driver impedance RON is defined by the value
ofthe external reference resistor RZQ as follows:
RON34 = RZQ / 7 (nominal 34.4ohms +/-10% with nominal RZQ=240ohms)
The individual pull-up and pull-down resistors (RONPu and RONPd) are defined as follows:
RONPu = [VDDQ-Vout] / | Iout | ------------------- under the condition that RONPd is turned off (1)
RONPd = Vout / | Iout | -------------------------------under the condition that RONPu is turned off (2)
