Does TI or SVA offer any clock distribution parts like the cdclvp12xx that have

pre-emphasis and/or equalization built-in to help compensate for dielectric

and copper losses? 

I have a customer that currently uses this family of products and is investigating an option where the signal may need to be send a long distance, possibly 20 ft or so.

We offer products, such as repeaters with these features, but I am not aware of any clocking products.
