In some devices not all tiles have an external clock input.

  • In Gen 1/Gen 2 devices, all tiles have an external clock input.
  • In Gen 3 devices, all RF-ADC tiles have an external clock input. In tiles featuring Quad RF-DACs, all RF-DAC tiles have an external clock input. If only Dual RF-DAC tiles are present, the odd RF-DAC tiles (RF-DAC Tile 1 and 3) do not have an external clock input.
  • In DFE and XCZU42DR devices, the bottom RF-ADC tile (RF-ADC Tile 0) does not have an external clock input. All other tiles have an external clock input.

Enabled tiles without an external clock input should be configured to receive their clock from another tile on the device. In Gen3/DFE, any tile without an external clock input needs to get its clock from the internal distribution
