temperature range, measurement referenced to frequency
observed with fref=(fmax+fmin )/2, Vs=3.3V, VC=1.65V,
load=50Ω and temperature variable speed less than 2°C per
minute.
Ageing: Vs, VC, TA constant measurement referenced to
frequency observed with TA=25°C, Vs=3.3V, VC=1.65V,
load=50Ω and after 30 days of operation.
