NOTES:
1. Stresses beyond those listed under “Absolute Maximum Rating” may cause permanent damage to the module. These are stress ratings only and functional operation of the device at these or any other
conditions beyond those indicated under “Operating Specifications” is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
2. Requires external regulation and supply decoupling.
3. Cold Power-up.
4. Holdover will be re-calculated with each successful lock.Yearly aging represents 1 continuous year in Holdover.
