[1] Includes all stability effects for the 1-year calibration interval and Tcal ±5 °C temperature range applicable to all specifications.
[2] Specifications apply only if Internal Frequency Reference operation is selected. With External Frequency Reference operation
selected, the frequency of the Frequency Reference Output is locked to the signal applied to the Frequency Reference Input.
