Artix-7 FPGAs Data Sheet: DC and AC Switching Characteristics
Note: In Figure 4, differential peak-to-peak voltage = single-ended peak-to-peak voltage x 2.
Table 51 summarizes the DC specifications of the clock input of the GTP transceiver. Consult 7 Series FPGAs GTP Transceiver
User Guide (UG482) for further details.
