Frequency vs. temperature characteristics has its maximum at room temperature, for both higher and lower temperatures

the frequency decreases. Therefore, to reach symmetrical tolerances, the devices are factory-trimmed at room temperature

to the frequency value close to higher tolerance limit. See Typical operating characteristics.

The specified values are for the recommended configuration, i.e. parts properly soldered on PCB, with 0.1 µF ceramic

reflections; see output waveform screenshots for various conditions). Recommended is usage of the active scope probe

that adds around 1 pF of the load capacity to the total load and having frequency counter connected to the scope output as

input capacitance of the counter is typically in tens of pF. Installing the device in a socket may have an influence on the

frequency and repeatability as well, depending on quality of its contacts.
