= 0°C to 70°
NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium
has been reached under these conditions. For additional information, refer to the PCI Express Application Note section in the datasheet.
NOTE 1: Refer to the Phase Noise Plot.
