10.8 34 ohm Output Driver DC Electrical Characteristics
A functional representation of the output buffer is shown in Figure 96. Output driver impedance RON is
selected by bits ―D .I. C‖ A1 and A5 in the MR1 Register. Two different values can be selected via MR1
settings:
RON 34 = R ZQ / 7 (nominal 34.3 Ω ±10% with nominal R ZQ = 240 Ω)
RON 40 = R ZQ / 6 (nominal 40.0 Ω ±10% with nominal R ZQ = 240 Ω)
The individual pull-up and pull-down resistors ( RON Pu and RON Pd ) are defined as follows:
RON Pu =
RON Pd =
