An oscillator that derives its resonance from the quantized energy levels of atoms or molecules. A bound system, like an atom, must obey the principles of quantum physics, which state that its energies must have discrete values.
An atom can be propelled from one energy level to a higher one by an electromagnetic field at a specific frequency, or it can be lowered from a high energy level to a lower level by generating energy. The difference between the two energy levels of an atomic oscillator, divided by Planck’s constant, h, determines its resonance frequency.
The atomic oscillator operates on the premise that since every atom of a given element is similar, every time it absorbs or releases energy, it should do so with the exact same frequency.
Theoretically, counting the oscillations of the atom’s oscillations allows one to calculate the passage of time. The cesium atom serves as the source of resonance frequency for the national frequency standards created by NIST and other laboratories, which frequently employ cesium fountain technology.
Atomic oscillators made of rubidium are the most affordable and widely used; nevertheless, considerably less often produced versions made of cesium beam and hydrogen maser are also offered for sale.
The Global Embedded Atomic Oscillators market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Microchip’s Embedded atomic oscillators are the product of cutting-edge research, cutting-edge engineering and packaging, excellent manufacturing, and integrated software design. They provide exceptional performance and unmatched accuracy, stability, and reliability in the most difficult situations.
These oscillators retain accurate frequency and time during prolonged holdover periods during GNSS outages or for situations where GPS is intrinsically absent. They combine low drift rates, excellent short-term stability, and frequency stability with temperature fluctuations.
Microchip’s board-mountable integrated atomic oscillators are perfect for portable, battery-powered applications where electricity is scarce and exact frequency is needed right away after powering up.
These systems deliver atomic clock accuracy together with minimal size, weight, and power and are perfect for a variety of commercial, industrial, space, and defence applications where performance and ruggedness are important. They also have built-in 1 PPS disciplining capabilities.
