unless otherwise noted.
NOTE: The cycle-to-cycle jitter on the input will equal the jitter on the output. The part does not add jitter.
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.
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.
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.
