- Microchip has announced the latest in its line of miniature atomic clocks. It offers a wide range of operating temperature
- It features a low output frequency of up to 1Hz
New atomic clock sample
Offers frequency stability over a wide temperature range
“ Its combination of the 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 hold-over during GNSS outages or for applications where large rack-mount clocks are not possible. ”
Holdover of up to 48 hours
The company informed that the clock can provide sub-microsecond hold-over for up to 48 hours. This prediction was made assuming the phase/frequency offset to be zero. The product is also claimed to run for 30 days consistently with reaching the hold-over condition. The favourable temperature for maximum clock stability can be achieved at a static temperature of 25˚C.
Maintains the same size as of opened crystal oscillator
This atomic clock comes in package dimensions of 50.8mm x 50.8mm x 47 mm. The new clock is intended to be the same size as an opened crystal oscillator (OCXO). The device can provide an output power of up to 6.3W. According to Microchip,
“ MAC-SA5X is designed with the same footprint as the previous generation miniature atomic clock technology. Also, it provides backward compatibility with its predecessor MAC-SA.3Xm family. ”
This atomic clock is targeted for precision-based applications. These applications are generally hard-real time systems that can not bear any delay in the running applications. Microchip has made the device available for pre-sampling.
