How to connect our Oscillator output and Xilinx® FPGA transceiver reference clock input

  • Please note the following design point when you connect our product and Xilinx® FPGA.
  • [1]Provide AC coupling bitween the oscillator output pins and the dedicated clock input pins.
    < Effect >
    • DC current is blocked between the oscillator and the FPGA clock input pins.
    • Power consumption of both parts is reduced.
    • The AC coupling capacitor forms a high-pass filter with the on-chip termination that attenuates a wander of the reference clock.
  • [2]Provide a dedicated point-to-point connection between the oscillator and clock input pins.
  • [3]Keep impedance discontinuities on the differential transmission lines to a minimum.
    < Effect >
    • A clock waveform distortion by reflection is suppressed to a minimum.
  • [4]Keep two transmission lines to same length and width.
    < Effect >
    • Common-mode noise is absorbed and rejected, when the phase difference between two signals is kept 180 degrees.
