NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. Device will meet specifications after thermal equilibrium has
been reached under these conditions.
NOTE All parameters measured at 250MHz unless noted otherwise.
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential cross
points.
NOTE 4: Defined as skew between outputs on different devices operating at the same supply voltage, same temperature and with equal load
conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross points.
