Notes:
1. Device powered and unconfigured.
2. Currents for conditions other than values specified in this table can be obtained by using the XPOWER Estimator (XPE) or XPOWER
Analyzer (XPA) tools.
3. GTX transceiver quiescent supply current for an entire device can be calculated by multiplying the values in this table by the number of
available GTX transceivers.
4. Typical values are specified at nominal voltage, 25°C.
GTX Transceiver DC Input and Output Levels
Table 17 summarizes the DC output specifications of the GTX transceivers in Virtex-6 FPGAs. Consult the Virtex-6 FPGA
GTX Transceivers User Guide for further details.

Notes:
1. The output swing and preemphasis levels are programmable using the attributes discussed in the Virtex-6 FPGA GTX Transceivers User
Guide and can result in values lower than reported in this table.
2. Other values can be used as appropriate to conform to specific protocols and standards.
