In the Virtex II User Guide (v1.6.1) on pg 200, it states ...
DCI in Virtex-II Hardware DCI only works with certain single-ended and differential I/O standards. DCI supports the following Virtex-II standards: LVDCI, LVDCI_DV2, GTL_DCI, GTLP_DCI, HSTL_I_DCI, HSTL_II_DCI, HSTL_III_DCI, HSTL_IV_DCI, SSTL2_I_DCI, SSTL2_II_DCI, SSTL3_I_DCI, and SSTL3_II_DCI, LVDS_25, LVDSEXT_25, LVDS_33_DCI, LVDS_25_DCI, LVDSEXT_33_DCI , and LVDSEXT_25_DCI.
Note the reference to LVDS_33_DCI! In several other places I have found it stated that if you use DCI with LVDS, then you must have Vcco = 2.5V, or it won't work correctly.
I would like to try DCI with my Virtex II LVDS inputs with Vcco = 3.3V, and have it work correctly. Can this be done? Or is there a typo in the User's Guide.
