Note 1: I/O supply of 3.3V is preferred.
Note 2: The above power consumption assumes that all ports are functioning at Gen2 (5.0 GT/S) speeds. Power consumption can be
reduced by turning off unused ports through software or through boot EEPROM. Power savings will occur in V
V
off port is close to zero. For example, if 2 ports out of 8 are turned off, then the power savings for each of the above three power rails can be
calculated quite simply as 2/8 multiplied by the power consumption indicated in the above table.
Note 3: Using a port in Gen1 mode (2.5GT/S) results in approximately 18% power savings for each power rail: V
