The Block Diagram of the System is bit more complicated as it should be: the CLKOUT block is small IP Core that sends a global clock to IO buffer with no phase delay , that is uses DDR IO using DDR I/O FlipFlop. This clock has exactly same phase as the TXD outputs to PHY. This output was only used for measurements, it is not wired to the PHY ref clock at all.
