Note: dRONdT and dRONdV are not subject to production test but are verified by design and characterization.
5.8 On-Die Termination (ODT) Levels and I-V Characteristics
5.8.1 On-Die Termination (ODT) Levels and I-V Characteristics
On-Die Termination effective resistance RTT is defined by bits A9, A6, and A2 of the MR1 Register.
ODT is applied to the DQ, DM, DQS/DQS, and TDQS/TDQS (x8 devices only) pins.
A functional representation of the on-die termination is shown in the following figure. The individual pull-up and pull-down
resistors (RTTPu and RTTPd) are defined as follows:
RTTPu = [VDDQ - Vout] / | Iout | ------------------ under the condition that RTTPd is turned off (3)
RTTPd = Vout / | Iout | ------------------------------ under the condition that RTTPu is turned off (4)
5.8.2 ODT DC Electrical Characteristics
The following table provides an overview of the ODT DC electrical characteristics. The values for RTT60Pd120,
RTT60Pu120, RTT120Pd240, RTT120Pu240, RTT40Pd80, RTT40Pu80, RTT30Pd60, RTT30Pu60, RTT20Pd40,
RTT20Pu40 are not specification requirements, but can be used as design guide lines:
