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: The listed numbers are for the IC only. Specify the crystal for the value at VCON = 1.65V and add the PCB & package

parasitic. A round number (i.e. 12pF) can be achieved by adding external capacitors. Try to add the same value to XIN and XOUT, and please note,

that frequency pulling and oscillator gain may decrease.
