Notes:
1.
Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
2.
The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3.
Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB.
4.
The circuit is designed to meet the AC and DC specifications shown in the above table after thermal equilibrium has been established.
5.
All phase
noise measurements were taken with an Agilent 5052B phasenoise system.
6.
Defined as skew between outputs at the same supply voltage and with equal load conditions and same frequency; measured at the output
differential crossing points.
7.
Measured using a 25MHz crystal as the input reference source. If using an external reference input, use a low phase noise source. With an
external reference, the phase noise will follow the input source phase noise up to about 1MHz offset frequency.
