NOTE: 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.
7. Measured by forcing VINPP (MIN) from a 50% duty cycle clock source. Connect a 475 W resister from IREF (Pin 1) to GND. All outputs loaded
50 W to GND per Figure
6.8. Measured from the input pair crosspoint to each single output pair crosspoint across temp and voltage ranges per Figure
3.9. Duty cycle skew is measured between differential outputs using the deviations of the sum of Tpw- and Tpw+.
10.Skew is measured between outputs under identical conditions @ 50 MHz.
11. Phase noise integrated from 12 kHz to 20 MHz
