2.3.2.3. Package Loss and Crosstalk

The package loss for the Intel® Stratix® 10 E-Tile is summarized below for designers' end-to-end channel loss estimation/evaluation:
  • Impedance specification: 90 ohm +/- 10%
  • Maximum differential insertion loss: -3 dB (Tx or Rx) at the Nyquist frequency
  • Differential return loss: better than -15 dB up to the Nyquist frequency
  • Crosstalk (up to the Nyquist frequency)
    • NEXT < -60 dB
    • FEXT < -50 dB
