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.
All parameters are measured at 1.5GHz unless otherwise noted.
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at the output differential cross points.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Defined as skew between outputs on different devices operating at the same supply voltage, same temperature, same frequency
and with equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross points.
