Note: if no voltage is applied to the control voltage (pin1) it will be internally set. If a voltage is applied (even GND) to Pin 1, the oscillator will accept the external control voltage input. ## **Noise Parameters** |**Noise Parameters**|**Noise Parameters**| |---|---| |Short Term Stability (ADEV) typical|| |1 s|5.0E-11| |10 s|9.0E-12| |100 s|4.5E-12| |Phase Noise|(typ)| |-67 dBc/Hz|@ 1 Hz| |-95 dBc/Hz|@ 10 Hz| |-127 dBc/Hz|@ 100 Hz| |-140 dBc/Hz|@ 1kHz| |-148 dBc/Hz|@ 10 kHz| |-148 dBc/Hz|@ 100 kHz| ## **Material Parameters** ## **Environmental Parameters** |**Material Parameters**|| |---|---| |Termination Finish|Au| ||Kovar alloy| |Moisture Sensitivity Level (MSL)|Not Applicable| ## **Manufacturing Details** These products need to maintain thermal stability to obtain optimum performance. Large copper plates should be avoided under the device, or mount the device with 1 mm clearance from the PCB. Avoid airflow and do not attempt to mount heat sink to the device. The oscillator base plate runs hot: be aware that this may cause damage to other components in close proximity. Storage Temperature Range: -55 °C to 95 °C Base Plate Temperature: -30 to 85 °C Case Temperature (after 1 hr, ambient temp 25 °C, no ventilation): 55 °C typ.
