Output impedance matching input. This input is used to tune the device outputs to the system data
bus impedance. CQ, CQ, and Q
connected between ZQ and ground. Alternatively, connect this pin directly to V
minimum impedance mode. This pin cannot be connected directly to GND or left unconnected.
PLL turn off  active LOW. Connecting this pin to ground turns off the PLL inside the device. The timing
in the operation with the PLL turned off differs from those listed in this data sheet. For normal operation,
connect this pin to a pull up through a 10 K or less pull-up resistor. The device behaves in QDR I mode
when the PLL is turned off. In this mode, the device can be operated at a frequency of up to 167 MHz
with QDR I timing.
