All specifications are based on the test circuit shown below
Device will function over the storage temperature range (-40 to +85 deg C). However, specifications are only guaranteed at the
operating temperature of 25 deg C. The temperature coefficient will define the frequency shift over temperature.
This is the optimum impedance in order to achieve the performance shown
