PROCESS RECOMMENDATIONS
TABLE 6.0
Solder Reflow
The component solder used internal to this device has a melting point of
221
°C. The peak temperature inside the device should be less than or equal
to 220
°C for a maximum of 10 seconds
Wash
Ultrasonic cleaning is not recommended.
Notes
1.0
Inclusive of calibration, frequency vs. temperature stability, supply voltage change, load change, shock and vibration and
aging over 15 years, Vc=1.65 Vdc.
2.0
Referenced to Fo @ 25°C. Positive Slope.
3.0
Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all conditions over lifetime operation.
The APR is referenced to Fo.
4.0
Output is enabled with no connection on pin 2.
