MEMS Micro Atomic Clock
Micro Atomic Clock: MMAC™
The MEMS Micro Atomic Clock – MMAC™ is an atomic frequency reference offering a fantastic trade-off between compactness, power consumption and overall frequency stability performances.
At the core of the MMAC, a millimetric MEMS silicone structure encapsulates a cesium vapor (non-radioactive of course). The combination of this MEMS core and complex embedded digital electronics provides a very low long-term frequency drift, ie ±0.01ppb per day. It also gives less than ±1 ppb of frequency variation when temperature fluctuate between -40 °C and + 85 °C.
With a size of 40 x 35 x 22 mm and a consumption of less than 300 mW at -40°C, the MMAC-10 reaches the state-of-the-art of ultra-compact atomic clocks on the market. Currently in development, the MMAC-10 is not yet available for ordering but will be soon proposed for sampling or initial trials. Please contact us for any specific inquiry on this product.
