    Time-keeping specialist Symmetricom has developed the SA.3Xm family of miniature precision atomic clocks for applications short on space but requiring precision timekeeping and frequency control. The new atomic clock is available in two versions: the model SA.31m is suitable for mobile applications such as in UMTS base stations while the SA.33m is designed for long holdover applications, such as CDMA base stations. The new atomic clocks are about one-fifth the size of conventional rubidium atomic clocks.
