we want to use the AD9208-3000EBZ in combination with the zcu102 from xilinx.
Therefore we were looking through the schematics that can be found here:
The FMC connector shows that all the necessarry pins are alligned.
But on D4/D5 there are labels indicating "EXT_REFCLK_TO_FPGA+" and "EXT_REFCLK_TO_FPGA-" but these labels aren't appearing anywhere else in the document.
Are D4/D5 not connected or is this an error in the Schematics?
