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 Spartan-6 FPGA GTP Transceivers User Guide.
2. Voltages are specified for the temperature range of T_j = –40°C to +100°C.
3. The voltage level of MGTAVCCPLL must not exceed the voltage level of MGTAVCC +10mV. The voltage level of MGTAVCC must not exceed the
voltage level of MGTAVCCPLL.

Notes:
1. Typical values are specified at nominal voltage, 25°C, with a 2.5 Gb/s line rate, with a shared PLL use mode.
2. Values for currents of other transceiver configurations and conditions can be obtained by using the XPOWER Estimator (XPE) or XPOWER Analyzer
(XPA) tools.
