** Referenced to the midpoint between minimum and maximum frequency value over Operating Temperature Range.
NOTE: It is recommended that a 0.01µF bypass capacitor be connected between Vdd (Pin 4) and Ground (Pin 2) to minimize power supply noise.
It is recommended that an external 0.01µF AC-coupling capacitor be connected to output (Pin 3) of the device.
For the TXCO (I547), it is recommended that Pin 1 should not be left floating but be connected to Ground.
