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, 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 timing
in the DLL turned off operation is different from that listed in this data sheet.
