About This Document
The SA.45s user guide provides basic recommendations for designing products to use Microsemi's
SA.45s Chip-Scale Atomic Clock (CSAC). The guidelines in the document are generic because specific
product requirements vary from one application to the other.
This material consists of a brief description of SA.45s design supported by block diagrams, description of
environmental issues, installation guidelines, and unit operation.
