Part, connector and connector assembly.
Background technique
Crosstalk refers to when signal is propagated on the transmission line, because electromagnetic coupling adjacent transmission line is generated it is undesirable
Voltage noise interference.Signal transmits in the form of an electromagnetic wave in transmission line, and electromagnetic wave includes the electric and magnetic fields of time-varying, becomes
The electric and magnetic fields changed can generate inductive voltage and current in the transmission line of surrounding.And voltage and current is exactly the biography for receiving interference
The immediate cause of crosstalk performance in defeated line.
Crosstalk is to influence the another key factor of product transmission performance, and reducing crosstalk is always the design of high-speed-differential connector
Important directions, in some cases, to high speed performance transmission importance be even more than characteristic impedance.Especially in characteristic
In the case that impedance is relatively easy to guarantee, the transmission performance design of high-speed-differential connector is largely to the anti-string of connector
Disturb the design of ability.
Excessive crosstalk can generate two kinds of harmful influences: first, crosstalk can make the available characteristic impedance and biography of transmission line
Defeated speed changes, and influences system signal integrality, to change the transmission performance on transmission line；Second, crosstalk can be at it
Induced noise is introduced on its transmission line, further decreases signal integrity, and reduce noise margin.
