Specifications

Note:

1)

Initial calibration @ 25 C. Specifications at time of shipment after 48 hours of operation

2)

Frequency stability vs. change in temperature.

3)

Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C.

4)

Leave Pad 8 unconnected if enable / disable function is not required. When tri-stated, the output stage is disabled but the oscillator and

compensation circuit are still active (current consumption < 1mA).

5)

or best performance it is recommended that the circuit connected to this output should have an equivalent input capacitance of 15pF.
