PRODUCTS & TECHNOLOGY ABOUT US HISTORY INVESTOR RELATIONS VENDORS NEWS AND EVENTS CAREERS CONTACT US QUARTZ MASTER CLOCKS A Master Clock (based on precision Quartz Crystal Oscillators or Rubidium Vapor Atomic Oscillators) is intended to be used where timing is critical, but the host device may need to perform autonomously. For example, a satellite requires an internal clock, which is synchronized with clocks on earth. Since the satellite can be out of touch with ground stations from time-to-time and when contact is re-established, both the internal and earth clocks must be in perfect synchronization to maintain communication.
