Output Impedance Matching Input. This input is used to tune the device outputs to the system
data bus impedance. CQ, CQ, and Q
resistor connected between ZQ and ground. Alternatively, this pin can be connected directly to
V
GND or left unconnected.
DLL Turn Off, Active LOW. Connecting this pin to ground turns off the DLL inside the device.
The timing in the DLL turned off operation is different from that listed in this data sheet. For
normal operation, this pin can be connected to a pull up through a 10 Kohm 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.
