Microchip Launches the Subsequent Technology of its Low-Noise Chip-Scale Atomic Clock That includes a Decrease Profile Top of Much less Than ½ Inch

The Low-Noise Chip-Scale Atomic Clock, mannequin SA65-LN, permits frequency mixing for battery-powered gadgets

Builders want ultra-clean timing gadgets for aerospace and protection functions the place measurement, weight, and energy (SWaP) constraints are essential. A Chip-Scale Atomic Clock (CSAC) is an important reference for these programs, offering the required exact and steady timing the place conventional atomic clocks are too giant or power-hungry and the place different satellite-based references could also be compromised. Microchip Know-how at the moment broadcasts its second technology Low-Noise Chip-Scale Atomic Clock (LN-CSAC), mannequin SA65-LN, in a decrease profile top and designed to function in a wider temperature vary, enabling low section noise and atomic clock stability in demanding circumstances.

Microchip has developed its personal Evacuated Miniature Crystal Oscillator (EMXO) know-how and built-in it right into a CSAC, enabling the mannequin SA65-LN to supply a diminished profile top of lower than ½ inch, whereas sustaining an influence consumption of <295 mW. The brand new design is perfect for aerospace and protection mission-critical functions similar to cell radar, dismounted radios, dismounted IED jamming programs, autonomous sensor networks and unmanned automobiles because of its compact measurement, low energy consumption and excessive precision. Working inside a wider temperature vary of -40°C to +80°C, the brand new LN-CSAC is designed to take care of its frequency and section stability in excessive circumstances for enhanced reliability.

“A big development in frequency know-how, our subsequent technology LN-CSAC offers distinctive stability and precision in a remarkably compact kind,” mentioned Randy Brudzinski, company vice chairman of Microchip’s frequency and time programs enterprise unit. “This system permits our clients to attain superior sign readability and atomic-level accuracy, whereas additionally benefiting from diminished design complexity and decrease energy consumption.”

The LN-CSAC combines the advantages of a crystal oscillator and an atomic clock in a single compact system. The EMXO provides low-phase noise at 10 Hz < -120 dBc/Hz and Allan Deviation (ADEV) stability <1E-11 at a 1-second averaging time. The atomic clock offers preliminary accuracy of ±0.5 ppb, low frequency drift efficiency of <0.9 ppb/mo, and most temperature-induced errors of < ±0.3ppb. Collectively, the LN-CSAC can save board house, design time and general energy consumption in comparison with designs that characteristic two oscillators.

The crystal sign purity and low-phase noise of LN-CSAC are designed to make sure high-quality sign integrity, which is important for frequency mixing. The atomic-level accuracy permits for longer intervals between calibrations, which may help prolong mission durations and probably scale back upkeep necessities.

Microchip’s merchandise for aerospace and protection are designed to satisfy the stringent necessities of those markets, providing excessive reliability, precision and sturdiness. The corporate’s options embody microcontrollers (MCUs), microprocessors (MPUs), FPGAs, energy administration, reminiscence, safety and timing gadgets that guarantee optimum efficiency in mission-critical functions similar to avionics, radar programs, and safe communications.
