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 V
INPP
(MIN) from a 50% duty cycle clock source. Measurements taken with outputs in either 1X (all outputs loaded
50 W to GND) or 2X (all outputs loaded 25 W to GND) configuration, see Figure 9. For 1X configuration, connect I
REF
to GND, or for 2X
configuration, connect I
REF
to V
CC
. Typical gain is 20 dB.
8. Measured from the input pair crosspoint to each single output pair crosspoint across temp and voltage ranges.
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 transition @ 133 MHz.
11. Additive RMS jitter with 50% duty cycle clock signal using phase noise integrated from 12 KHz to 33 MHz
