Interface and Termination Recommendations
Figure 3 shows a +3.3 V coupling scheme. Also present
are power supply filtering arrangements which comply
with the recommendations of the small form factor
multisource agreement. Such a compliance ensures
noise rejection compatibility between transceivers from
various vendors.
