The Molex NeoPress high-speed mezzanine system, now available from Mouser Electronics, provides compliant-pin termination while minimizing near-end and far-end crosstalk
, matching the signal integrity of NeoScale SMT connectors.
New technology solves this problem by providing compliant-pin termination while minimizing near-end and far-end crosstalk
, matching the signal integrity of SMT connectors.
In particular, the four most important terms for two coupled, single-ended transmission lines are the characteristic impedance, the effective dielectric constant, the near-end crosstalk coefficient and far-end crosstalk
However, the transmission performance of xDSL is heavily influenced by various disturbances and noises in multi-pair and multi-quad metallic cables and especially by far-end crosstalk
The theoretical results of near- and far-end crosstalk
characteristics obtained by the proposed approach and the results using a commercial solver (HFSS), and the measured results are shown in Figs.

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
The measurement setup emulates the crosstalk behavior at the receiver side so the evaluation targets far-end crosstalk
All the possible pair combinations for both alien near-end and far-end crosstalk
were measured and evaluated over the frequency range up to 500 MHz.
Which is more likely, that the corners are producing the dips or far-end crosstalk
is producing the dips?
The model UFX-9835 is a test instrument that generates near-end crosstalk (NEXT) and far-end crosstalk
(FEXT) for production testing of DSL modems.
