GTP Transceiver Specifications (Only available in the XC7Z012S and XC7Z015)
GTP Transceiver DC Input and Output Levels
Table 85 summarizes the DC output specifications of the GTP transceivers in the XC7Z012S and XC7Z015. Consult the
7 Series FPGAs GTP Transceiver User Guide (UG482
) for further details.
Note: In Figure 21, differential peak-to-peak voltage = single-ended peak-to-peak voltage x 2.

Notes:
1. The output swing and preemphasis levels are programmable using the attributes discussed in the 7 Series FPGAs GTP Transceiver User
Guide (UG482
) and can result in values lower than reported in this table.
2. Voltage measured at the pin referenced to GND.
3. Other values can be used as appropriate to conform to specific protocols and standards.
