Miniature Atomic Clock (MAC)

Microchip’s next-generation MAC-SA5x miniaturized rubidium atomic clock produces a stable time and frequency reference that maintains a high degree of synchronisation to a reference clock, such as a GNSS-derived signal, despite static g-forces or other factors. Its combination of low monthly drift rate, short-term stability and stability during temperature changes allow the device to maintain precise frequency and timing requirements during extended periods of holdover during GNSS outages or for applications where large rack-mount clocks are not possible.

Chip Scale Atomic Clock (CSAC)

Unmatched combination of breakthroughs – reduced size, weight and power consumption – brings the accuracy and stability of atomic clocks to portable applications.

The Microchip SA.45s CSAC is the world’s first commercially available chip scale atomic clock, providing the accuracy and stability of atomic clock technology while achieving true breakthroughs in reduced size, weight and power consumption.
