Virtex-II/Virtex-II Pro LVDS - Is on-chip termination available?


Is on-chip termination available for Virtex-II and Virtex-II Pro LVDS inputs?


Virtex-II and Virtex-II Pro offer unique solutions as follows:


Internal LVDS termination can be implemented with DCI (digitally controlled impedance).

The DCI LVDS solution is available beginning with 5.1i Service Pack 1 available at:


1. You must use DCI LVDS with a VCCO of 2.5V. A 3.3V termination causes signal behavior to deviate from LVDS standard specifications.

2. DCI LVDS termination has a power cost of 62.5 mW per termination (i.e., per input pair).
