Re: Differential output buffers

Syed,

Thanks for the quick response. Are there other tools out there that support
IBIS v3.2 which would be better for the differential? Also, I misstated my
initial question. I'm really interested in differential devices in general,
drivers and receivers. I was able to at least get some results for a driver
using s2ibis2, although not very good ones. But for the receiver I don't
see how it can work, because s2ibis2 only gives one input pulse.

Thanks again for any help you can give me on this. I hope these questions
aren't too trivial, while I'm familiar with using IBIS models, I'm new to
actually trying to make my own. I really appreciate the assistance.

Regards,
Bill Clifford
