Yes..make a centre tapped capacitor with 50R resistance foils either side of
the centre tap. Funny things, these perceived physical limits. How much
money are you prepared to throw at the problem??

Subject: [SI-LIST] : Physcially-small far-end LVDS terminations?
> I want to use the typical LVDS termination where you have two 50-ohm
resistors in series placed between the two lines of the LVDS diff. pair and
also have a cap at the junction of the resistors to ground. I have a
jillion LVDS pairs to terminate at a high-pin-count ASIC, and I'm looking to
squeeze more terminations per square inch. (There's no hope of putting the
terminations inside the ASIC at this point.) I'm hoping some company makes
a single three-pin part the has those two resistors and a cap even if not
specifically for termination use.
