This equation contains the power sum FEXT budget for the connector in the numerator of the second exponent term.
In Figure 9, the S-parameters of insertion loss, return loss, near end crosstalk (NEXT), and far end crosstalk (FEXT) are shown.
al., 2002) the received power spectral densities (PDSs) of NEXT and FEXT due to more than one crosstalk disturber for n interfering signals of the same kind become
The FEXT crosstalk signal is created in a similar manner as the NEXT crosstalk signal (its spectrum is presented on fig.
Because FEXT is dispersed similar to the desired received signal, canceling it can require a significant amount of signal processing hardware.
With a rise time of 25 psec, typical of a high-end PCIe gen II part, and a coupled length of 2", the FEXT would be about 20%.
The eye-pattern measured from the circuit with the compensated capacitor significantly reduces the jitter due to the improved FEXT on the circuit.
Far-end crosstalk normalized by subtracting the attenuation of the disturbing pair from FEXT induced on an adjacent pair.
* Far end crosstalk (FEXT) is a measure of the amount of signal from a device on one end of the cabling system that couples into an adjacent receive circuit in a device on the other end of the cabling system.
While the influence of near-end (NEXT) crosstalk can be partially limited by using several different frequency bands for both directions (there are several various frequency plans, scenarios, for VDSL2 lines), the influence of far-end crosstalk (FEXT) cannot be reduced so easily.
IF YOU HAVE ever used a 2D field solver to calculate the far-end crosstalk coefficient (FEXT) in a pair of microstrip transmission lines--a critical part of every design with surface traces!--you've probably encountered what appears to be a typo or a bizarre result.
