[SI-LIST] Re: Two Layer routing

Sunil,
  With not a lot of field containment possible, both of them are much worse in 
a two layer board. Which one is more troublesome depends on the impedances of 
the source and the victim circuits. However, with all the large loops formed by 
the traces to route the signals, inductive crosstalk could be more troublesome. 
This also results in increased emissions and susceptibility too.
   
  Thanks,
  Ram

  Hi Friends ,
PCB routing in a two layer PCB with out power planes is definitely
not advisable.Noisy ,EMI .....

I believe cross talk will be worse too.Is the capacitive coupling
or the inductive coupling which makes the cross talk bad in the two layer
cases ?

Could some one pls explain this.

Thanks in advance!!
