FPD-Link III CE issue

Hi,everyone.

I have some question about EMC of FPD-LINK III.

We use DS90UB925Q to transport LVDS signal to DS90UB928Q,and in EMC test,conducted emissions from components/modules – current probe method,frequency of 86M is exceed the limit(CISPR 25 2008 CLASS 3,BROADCAST）

We use 2m longs LVDS cable in the test.

I used spectrum analyser to detect LVDS signal,and i got spectrum waveform as follow:

I doubt that LVDS singal cause the exceed of 86M,and if I change the length of cable,the exceed frequency will

drift(45M and so on,depends on the length).

LVDS signal waveform:

So, will FPD-LINK III cause EMC problem?
