IO
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, this pin can be connected directly to V
enables the minimum impedance mode. This pin cannot be connected directly to GND or left uncon-
nected.
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 is different from those listed in this data sheet. For normal
operation, this pin can be connected to a pull up through a 10KΩ or less pull up resistor. The device
behaves in DDR-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 DDR-I timing.
