DESCRIPTION
NAME
NO.
VIN
3
The positive input voltage power node to the module, which is referenced to common GND.
This is the common ground connection for the VIN and VTT power connections. It is also the 0-VDC reference for
GND
1
the control inputs.
The module senses the voltage at this input to regulate the output voltage, VTT. The voltage at VREF is also the
reference voltage for the system bus receiver comparators. It is normally set to precisely half the bus driver supply
VREF
2
voltage (VDDQ÷ 2), using a resistor divider. The Thevenin impedance of the network driving the VREF pin should
not exceed 500 . See the Typical DDR Application Diagram in the Application Information section for reference.
This is the regulated power output from the module with respect to the GND node, and the tracking termination
supply for the application data and address buses. It is precisely regulated to the voltage applied to the module's
VTT
6
VREF input, and is active active about 20 ms after a valid input source is applied to the module. Once active it will
track the voltage applied at VREF.
The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a low-level
ground signal to this input turns off the output voltage, VTT. Although the module is inhibited, a voltage, VDDQ will
be present at the output terminals, fed through the DDR memory. When the Inhibit is active, the input current
Inhibit
4
drawn by the regulator is significantly reduced. If the Inhibit pin is left open circuit, the module will produce an
output whenever a valid input source is applied. See the Typical DDR Application Diagram in the Application
Information section for reference.
