Frequency Tolerance (measurement referenced to frequency

observed with TA=25°C, Vs=3.3V and within 30 days after

ex-works)

Frequency Stability: TA varied across the operating

temperature range, measurement referenced to frequency

observed with TA=25°C, Vs=3.3V, load=10kΩ//10pF and

temperature variable speed less than 2°C per minute.

Ageing: TA=25°C, Vs=3.3V and after 1hr of operation.

Supply Voltage Variation (measurement referenced to

frequency observed with TA=25°C, Vs varied from 3.13V to

3.47V and load=10kΩ//10pF): ±0.1ppm max

Load Variation (5 load change measurement referenced to

frequency observed with TA=25°C, Vs=3.3V and

load=10kΩ//10pF): ±0.1ppm max

Short Term Stability (@ 25°C after 10mins power on): 5E-10/s
