R
The total impedance of the LVTTL/LVCMOS driver added to the series termination
resistor R
undershoot. An IBIS simulation is advised for calculating the exact value needed for R
The connection scheme shown in
performance may be degraded by R
value and performance with an IBIS simulation.
When designing with the LVDCI_33 standard:
•
•
•
In addition, changing the slew rate from fast to slow and/or reducing the current drive
could significantly reduce overshoot and undershoot.

External Device
LVTTL/
LVCMOS
Driver
The output drive strength and slew rates are not programmable. The output
impedance references the VRP and VRN resistors, and the output current is
determined by the output impedance.
If only LVDCI_33 inputs are used, it is not necessary to connect VRP and VRN to
external reference resistors. The implementation pad report does not record VRP and
VRN being used. External reference resistors are required only if LVDCI_33 outputs
are present in a bank.
LVDCI_33 is compatible with LVTTL and LVCMOS standards only.
