Output Impedance Matching Input. This input is used to tune the device outputs to the system data bus
impedance. CQ, CQ and Q
between ZQ and ground. Alternately, this pin can be connected directly to V
minimum impedance mode. This pin cannot be connected directly to GND or left unconnected.
DLL Turn Off − Active LOW. Connecting this pin to ground turns off the DLL inside the device.The timings
in the DLL turned off operation are different from those listed in this data sheet. For normal operation, this
pin can be connected to a pull up through a 10 KΩ or less pull up resistor. The device behaves in QDR-I
mode when the DLL is turned off. In this mode, the device can be operated at a frequency of up to 167
MHz with QDR-I timing.
