sampling clock through long PCB trace

Hi all,

 

I want to route a data sampling clock ( 500MHz~1000MHz ) with about 20 inch pcb trace, from one board to another through backplane.

Is it feasible? How about the jitter degradation of the clock? There are a lot of digital parts on the board with ADC, an FPGA with tens of GTH traces to the backplane. I really doubt this method, but someone urge me to do so.

 

Does anybody have any idea or experience on this kind of issue? Or any suggestion about how to route the signal?

 

best regards
