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.
2.2
Intended Audience
This document is intended for engineers and telecommunications professionals who are designing,
installing, operating, or maintaining time, frequency, and synchronization systems having a requirement
for a low profile and highly precise frequency generator.
To use this document effectively, you should have a good understanding of digital telecommunications
technologies and analog frequency generation and synthesis techniques.
