Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the
device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other
conditions above the operational limits noted in this specification is not implied.
*
Note
: Operating Temperature is guaranteed by design for all parts (COMMERCIAL and INDUSTRIAL), but tested for COMMERCIAL grade only.

Note
: Crystal Loading rating: 17.7pF is the loading the crystal sees from the XO chip. It is assumed that the crystal will be at nominal frequency at this
load. If the crystal requires less load to be at nominal frequency, then a capacitor can placed in series with the crystal. If the crystal requires more
load to be at nominal frequency, capacitors can be placed from XIN and XOUT to ground. This however may reduce the oscillator gain.
