Serial data rate in the -5 speed grade is limited to 2.0 Gb/s in both wirebond and flipchip packages.
UI = Unit Interval
For serial rates under 1 Gb/s, the 3X (or greater) oversampling techniques described in
receive jitter tolerance specifications defined in this data sheet.
The oversampling techniques described in
