[SI-LIST] Ferrite Beads on Differential Signal Lines?

SI-List,
I haven't seen any literature concerning using ferrite beads on each signal
line of a differential pair.
Usually only a common-mode choke is used to reduce common-mode EMI.
Can ferrite beads be used on a differential pair to increase the the rise
time of the signal and reduce unnecessary high-frequency content that may
radiate?
The two ferrite beads would be sized to allow the bandwidth necessary for
the differential signal's highest data rate.
Thanks,
Craig Francis
