The SA65 Chip Scale Atomic Clock (CSAC) provides wide operating temperatures, fast warm-up/atomic-lock and superior frequency stability in extreme environments. Suitable for military and industrial systems requiring ultra-high precision and low-power consumption. The SA65 is form-, fit- and function-compatible with the SA.45s, while improving performance and environmental insensitivity.
