CQ
Output-
Clock
CQ is referenced with respect to C
. This is a free running clock and is synchronized to the Input
clock for output data (C) of the DDR-II. In the single clock mode, CQ is generated with respect to
K. The timings for the echo clocks are shown in the AC Timing table.

K. The timings for the echo clocks are shown in the AC Timing table.
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
V
DDQ
, which enables the minimum impedance mode. This pin cannot be connected directly to
GND or left unconnected.
DLL Turn Off - Active LOW
. Connecting this pin to ground will turn off the DLL inside the device.
The timings in the DLL turned off operation will be different from those listed in this data sheet.
For normal operation, this pin can be connected to a pull-up through a 10-Kohm or less pull-up
resistor. The device will behave 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.
TDO for JTAG
.
TCK pin for JTAG
.
TDI pin for JTAG
.
TMS pin for JTAG
.
Not connected to the die
. Can be tied to any voltage level.
Address expansion for 144M
. Can be tied to any voltage level.
Address expansion for 288M
. Can be tied to any voltage level.
Reference Voltage Input
. Static input used to set the reference level for HSTL inputs and Outputs
as well as AC measurement points.
Power Supply
Power supply inputs to the core of the device
