A low-noise chip-scale atomic clock (LN-CSAC), the SA65-LN from Microchip, features a profile height of less than 0.5 in. (12.7 mm). Aimed at aerospace and defense applications where size, weight, and power are critical, the SA65-LN delivers precise and stable timing, along with low phase noise and atomic clock stability.

Based on Microchip’s Evacuated Miniature Crystal Oscillator (EMXO) and integrated into a CSAC, the SA65-LN consumes under 295 mW. It also operates within a temperature range of -40°C to +80°C, maintaining its frequency and phase stability. Low power consumption and a wide temperature range enable battery-powered operation under extreme conditions.
The LN-CSAC combines the stability of an atomic clock with the precision of a crystal oscillator in a compact design. The EMXO offers low phase noise of <−120 dBc/Hz at 10 Hz and an Allan Deviation (ADEV) of <1E-11 at a 1-second averaging time. The atomic clock provides ±0.5 ppb initial accuracy, frequency drift of <0.9 ppb/month, and temperature-induced errors of <±0.3 ppb.
The SA65-LN is available now in production quantities. It is supported by Microchip’s Clockstudio software tool, a GUI, and developer kit.
