This device has been designed to perform to the parameters of its data sheet. It has been tested to an elec-
trical specification designed to determine its conformance with these parameters. Due to process differ-
ences in the manufacture of this device, this device may have different performance characteristics than its
earlier version. These differences may cause this device to perform differently in your application than the
earlier version of this device.
The user should verify that the device oscillator starts and performs as expected. Adjusting the loading
capacitor values and/or the oscillator mode may be required.
