Featured Product

MAC-SA5X Miniaturized Atomic Clock

This rubidium-based atomic clock can meet your ultra-stable frequency and timing requirements when your design’s small size and power constraints prevent the use of larger lamp-based atomic clocks. This next-generation miniature atomic clock is completely redesigned for rapid warm-up time and to support a wider temperature range, making atomic clock timing available for an array of applications. New features including 1 PPS calibration and a versatile software interface to ease the design process. With its advancements in temperature stability and long-term drift rates, the MAC-SA5X enables frequency accuracy to be maintained for longer holdover durations.
