DS90UR905Q-Q1: Followed by a DS30BA101 into a LMH0394 finally the DS90UR906( Jitter Stack Up)

Part Number: DS90UR905Q-Q1
Other Parts Discussed in Thread: DS30BA101, LMH0394, TPS62160

Hello I am requesting some more information on the jitter stack up for other frequencies as i see it is more forgiving for 5MHz and 65MHz than the 10MHz...

I lose lock on the 906 but seem to have a pretty open eye coming from the CML out pins.

We are seeing this even with a short cable when the system reaches a high temperature maybe 45C ambient.

It seems that the 905 from the datasheet advertises a lot of jitter?

are original design runs the pclk about 24MHz and we have a high loss cable so we tried to lower the frequency to 12MHz and it seems to work when it is not warm leading me to question the specs on the 906 is the typical jitter tolerances based on high temp and max based on low temps?

Also for the clock source would the jitter be multiplied by the serializer?
