K
Input Clock
Positive Input Clock Input. The rising edge of K is used to capture synchronous inputs to the device
and to drive out data through Q[x:0]. All accesses are initiated on the rising edge of K.
K
Input Clock
Negative Input Clock Input. K is used to capture synchronous inputs being presented to the device and
to drive out data through Q[x:0].
CQ
Echo Clock
Synchronous Echo Clock Outputs. This is a free running clock and is synchronized to the input clock
(K) of the QDR-II+. The timings for the echo clocks are shown in the Switching Characteristics on page 24.
CQ

(K) of the QDR-II+.The timings for the echo clocks are shown in the Switching Characteristics on page 24.
ZQ
Input
Output Impedance Matching Input. This input is used to tune the device outputs to the system data bus
impedance. CQ, CQ, and Q[x:0] output impedance are set to 0.2 x RQ, where RQ is a resistor connected
between ZQ and ground. Alternatively, this pin can be connected directly to VDDQ, which enables the
minimum impedance mode. This pin cannot be connected directly to GND or left unconnected.
DOFF
Input
PLL Turn Off
Active LOW. Connecting this pin to ground turns off the PLL inside the device. The timings
in the PLL turned off operation differs from those listed in this data sheet. For normal operation, this pin
can be connected to a pull up through a 10 K
Ω 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.
TDO
Output
TDO for JTAG.
TCK
Input
TCK Pin for JTAG.
TDI
Input
TDI Pin for JTAG.
TMS
Input
TMS Pin for JTAG.
NC
N/A
Not Connected to the Die. Can be tied to any voltage level.
NC/144M
N/A
Not Connected to the Die. Can be tied to any voltage level.
NC/288M
N/A
Not Connected to the Die. Can be tied to any voltage level.
VREF
Input-
Reference
Reference Voltage Input. Static input used to set the reference level for HSTL inputs, outputs, and AC
measurement points.
VDD
Power Supply Power Supply Inputs to the Core of the Device.
VSS
Ground
Ground for the Device.
VDDQ
Power Supply Power Supply Inputs for the Outputs of the Device.
