NOTE: The device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared operating
temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values are applied
individually under normal operating conditions and not valid simultaneously.
NOTE: All parameters measured at 500MHz unless noted otherwise
NOTE 1: Measured from the differential input crossing point to the differential output crosspoint.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the output differential
crosspoint.
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 crosspoint.
