I'm currently working on a board design and I have to interface two VLSI

chips to each other that don't have exactly compatible level

characteristics. To be more precise I have a differential CML output of U(t)

= 1.8V +/- 0.400V * rect(t) being terminated 50 Ohm to Vref and a

non-standard differential Input which assumes U(t) = 1.15V +/- 0.125V *

rect(t) being 100 Ohm differentially terminated.

I first thought about AC coupling but that only kills my DC part but doesn't

come to solve the problem of incompatible swings. Maybe a resistor network

would be the right choice but I am not so firm on that topic. Any help,

suggestions and calculation examples would be appreciated.

Many thanks in advance and best regards,

Melanie
