How to Reduce Crosstalk in a PCB Layout

If the space in a pcb board is fixed and there are limited number of routing space on the board, what can i do in order to reduce crosstalk, because the traces are tightly coupled which can lead to noise issues. In this case it is a High Speed Board.

Solution:
I recommend using a multi-layer PCB with the adjacent layer below the TOP layer made of a full solid ground reference plane. Plus, I would not recommend to use a copper pour on the top layer when using the inner layer reference plane.

Are you planning to do ground pour? That can help with cross talk between signals

yes there will be ground pour thanks

As petr said using a multi layer pcb is a good option. But get advice from your fab house on layer stackup and material type

There will be no options for an optional stack up or materials. The engineer must choose from the PCB manufacturer portfolio and customise the design for it. Well, multilayer PCB is not a good option. It is the only option we have.
