Differences Between the Revision B and Revision C Boards
The major changes in revision C are summarized below:
1. The Revision C board includes eight pull-up resistors, R362-R369, to the DVI Rx signals placed close to the
LatticeECP3 device. These resistors are used for termination of the DVI’s TMDS signals and are not included
on the Revision B board.
