Hi All-
I am designing a high-speed loopback signal with an AC-coupling capacitor in
the path. I have designed them at lower speeds (sub-5GBs) but the current
design requires 10-20GBs.
The problem is that the capacitors that I plan to use don't provide performance
data beyond ~5GHz (http://www.yuden.co.jp/us/product/pdf/jmk063bj104kp.pdf).
My initial thought is that the capacitor will continue to work as a short for
increased data rates, but would like some feedback before I finalize the design.
1) Are there any concerns with AC-coupling capacitors at 10-20Gbs?
2) If so, can anybody provide recommendations for 0201 capacitors that will
work well at these data rates?
Thanks!
