minutes of operation, within 30 days after ex-works.
Frequency Stability: TA varied over operating temperature
range, measurement referenced to frequency observed with
fref=(fmax+fmin )/2, Vs=3.3V, VC=1.65V, load=15pF and
temperature variable speed less than 2°C per minute.
Ageing: Vs, TA constant, measurement referenced to
frequency observed with TA=25°C, Vs= 3.3V, VC=1.65V and
after 30 days of operation.
