Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings might cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied.
Exposure to Absolute Maximum Ratings conditions for extended periods of time might affect device reliability.

Notes:
1. Each voltage listed requires the filter circuit described in Virtex-6 FPGA GTX Transceivers User Guide.
2. Voltages are specified for the temperature range of T_j = –40°C to +100°C.
3. If a GTX Quad contains transceivers operating with a mixture of PLL frequencies above and below 2.7 GHz, the MGTAVCC voltage supply
must be in the range of 1.0V to 1.06V.

Notes:
1. Typical values are specified at nominal voltage, 25°C, with a 3.125 Gb/s line rate.
2. Values for currents of other transceiver configurations and conditions can be obtained by using the XPOWER Estimator (XPE) or XPOWER
Analyzer (XPA) tools.
