XAUI AC coupling
To all XAUI users vendors,
My appologies if this question has already been
AC coupling is part of the XAUI specification but no minimum
capacitor size has been included. At some point all XAUI users have to answer
the question of what capacitor size to use so I propose that it is included in
the specification. The format could be something like:
Maximum low frequency cut-off caused by AC coupling of XAUI
data: ____ Hz.
Minimum recommended AC coupling capacitor size in XAUI
channels: ____ Farads.
To fill in the blanks above requires some spectral information
of the 8B10B data going over the XAUI link. Can anyone help here?
