LVDCI_DV2
A controlled impedance driver with half impedance (source termination) can also provide
drivers with one half of the impedance of the reference resistors. This allows reference
resistors to be twice as large, thus reducing static power consumption through VRN/VRP.
The I/O standards supporting a controlled impedance driver with half impedance are:
LVDCI_DV2_15, LVDCI_DV2_18, and LVDCI_DV2_25.
illustrate a controlled driver with half impedance unidirectional and bidirectional
termination.
To match the drive impedance to Z
reference resistor R must be twice Z

There are no drive strength settings for LVDCI drivers. When the driver impedance is one-
half of the VRN/VRP reference resistors, it is indicated by the addition of DV2 to the
attribute name.
Table 6-9
R 0 = ½R VRN = ½R VRP = Z 0
lists the LVCMOS, LVDCI, and LVDCI_DV2 voltage specifications.
R 0 = ½R VRN = ½R VRP = Z 0
