CQ Referenced with Respect to C. This is a free-running clock and is synchronized to the input clock
for output data (C) of the QDR-II. In single clock mode, CQ is generated with respect to K. The timing for
the echo clocks is shown in

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. Alternatively, connect this pin directly to V
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 timing
in the operation with the DLL turned off differs from those listed in this data sheet. For normal operation,
connect this pin 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.
