Note: Electrical parameters are quaranteed 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.

Note1: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential cross points.

Note2: This parameter is defined in accordance with JEDEC Standard 65.

Note3: Please refer to the Phase Noise Plots.
