4. A separate sense trace should be used to
connect the VTT point of regulation, which is
usually the local bypass capacitor for load, to the
VTTSEN pin.
5. Separate sense trace should be used to
connect the VREF point of regulation to the
VTTREF pin to ensure the accuracy of the
reference voltage to VTT.
6. VDDQ should be connected to VREF Input
with wide and short trace if VDDQ is used as the
sourcing supply for VTT. An input capacitor of at
least 10μF should be added close to the VDDQ
pin and bypassed to GND if external voltage
supply is used as the VTT sourcing supply.
