If I have a design that have digital circuit and a small portion of RF.
There will be some signals going from digital into the RF and out from
the RF to the digital portion. If the digital portion has to be
impedance control at 50ohms, how should I go about doing such design to
ensure that both RF and Digital requirements are taken care of, without
causing any interference between these two circuits? What about the
ground? This design will be a 10-layer with the following stack-up :
L1 : signal
L2 : GND
L3 : +5V
L4 : signal
L5 : signal
L6 : signal
L7 : signal
L8 : +2.5V
L9 : GND
L10 : signal
I would appreciate any advise from you experts out there.
Thanks and regards.
