    3535As mentioned, each MGT column has two input clocks that are shared. Any of the MGT tiles in that column share the clocks. In column 0 the clock inputs are located at tile 102 and tile 105. In column 1, the inputs are tile 10 and tile 13. There is an elaborate clock multiplexer scheme on the board that lets the user choose three of the four clock inputs.
