[SI-LIST] Re: How to embedded and to deembedded the clock to serial signal, such as GE and PCI-E

How can you  reason out determinately  that  crosstalk was causing=20
Bit Error . By quieting  the  aggressive  line  and  then  error=20
eliminated .Verifying it ?
I guess that you were checking  bit  error on  machines  such as
Smartbit or similarities.  so  the bit error was  the last effect of
many causes and their combination. which including  almost all SI/PI
issues .  software  and hardware design bugs etc . all of these were
need to affirmed one by one .
In one case I had encountered  was  improper analog power filter
device resulting  Gbit  singal link error on   Verified :)
