Driver Impedance Control
Programmable Driver Impedance is implemented on the following output signals:
• CQ, CQ, Q, QVLD.
Driver impedance is programmed by connecting an external resistor RQ between the ZQ pin and VSS.
Driver impedance is set to the programmed value within 160K cycles after input clocks are operating within specification and RST
is de-asserted Low. It is updated periodically thereafter to compensate for temperature and voltage fluctuations in the system.

Notes:
1. ROUTL and ROUTH apply when 175 RQ  225.
2. The mismatch between ROUTL and ROUTH is less than 10%, guaranteed by design.
ODT Impedance Control
Programmable ODT Impedance is implemented on the following input signals:
• CK, CK, KD, KD, SA, R, W, D.
ODT impedance is programmed by connecting an external resistor RT between the ZT pin and VSS.
ODT impedance is set to the programmed value within 160K cycles after input clocks are operating within specification and RST
is de-asserted Low. It is updated periodically thereafter to compensate for temperature and voltage fluctuations in the system

Notes:
1. When MZT[1:0] = 00, ODT is disabled on all inputs. MZT[1:0] = 11 is reserved for future use.
2. RINL and RINH apply when 105 RT  135
3. The mismatch between RINL and RINH is less than 10%, guaranteed by design.
4. All ODT is disabled during JTAG EXTEST and SAMPLE-Z instructions.
Note: When ODT impedance is enabled on a particular input, that input should always be driven High or Low; it should never be
tri-stated (i.e., in a High- Z state). If the input is tri-stated, the ODT will pull the signal to VDDQ / 2 (i.e., to the switch point of the
diff-amp receiver), which could cause the receiver to enter a meta-stable state and consume more power than it normally would.
This could result in the device’s operating currents being higher.
