Pin Name
Pin Function Description
1, 2, 7 (4, 5, 10)
VDD
VDD. Input power for the LDO.
3, 6 (6, 9)
VTTFORCE
VTT Force Output.
4, 5, 8 (7, 8, 11)
VSS
Power Ground.
10 (12)
VTTSENSE
VTT Sense. Feedback for remote sense of the VTT voltage.
11 (13)
VREFIN
VREFIN. Alternative input for direct control of VTTOUT and VREFOUT.
12 (14)
SHDN
Shutdown. This active low shutdown turns off both VTT and VREFOUT. This
pin has an internal pull-down, and must be externally driven high for the IC to be
on.
13 (1)
VSSQ
Signal Ground.
14 (2)
VREFOUT
Buffered Voltage Reference Output.
15 (3)
VDDQ
VDDQ Input. Attach this pin to the VDDQ supply to generate VTT and
VREFOUT.
