DS90CR286: How long superfine coaxial line can we support

Hi Brian,

The Channel Link deserializer datasheet provides a specification called receiver skew margin (RSKM) that indicates the maximum amount of skew and jitter the deserializer can tolerate. You should choose a cable that does not violate this spec.

I recommend that you refer to this Channel Link design guide: https://www.ti.com/lit/ug/snla167/snla167.pdf?ts=1680814132361&ref_url=https%253A%252F%252Fwww.google.com%252F

There is additional information on link margin, and there is also a Data Rate vs. Cable Length section where you can see the typical performance using 3M MDR cable assemblies. 

Regards,

Cindy
