What is crosstalk and noise and how to fix it?

Question

Accepted Answer

Crosstalk is unwanted interference between signals on adjacent lines, while noise is random unwanted signals that can degrade performance.

Crosstalk occurs when signals on adjacent lines interfere with each other due to coupling effects.
Noise is random unwanted signals that can be caused by various sources such as electromagnetic interference or power supply fluctuations.
To fix crosstalk, techniques like spacing out lines, using shielded cables, and implementing signal integrity analysis can be employed.
To reduce noise, strategies like proper grounding, shielding sensitive components, and filtering out unwanted frequencies can be implemented.

Accepted Answer

Cross Talk: Switching of the signal in one net can interfere neighbouring net due to cross coupling capacitance. This effect is called cross talk.
Noise: It is caused due to crosstalk with other signals
to fix crosstalk: Shielding, Change the metal layers, Increase Spacing between two nets, Increase the drive strength, Add Buffers
