TMCNet: Symmetricom Unveils Miniature Atomic Clock

[September 23, 2007]

Symmetricom Unveils Miniature Atomic Clock

(Wireless News Via Thomson Dialog NewsEdge)
Symmetricom, a provider of precise time and frequency technologies that
accelerate the deployment and enable the management of next generation
networks, announced the SA.3Xm family of rubidium oscillators.

The SA.3Xm is one fifth the size, consumes less than half the power and
offers superior price-performance compared to current solutions. The
SA.3Xm represents a radical advance in atomic clock technology.

"Symmetricom has been the world leader in atomic clocks since 1985,"
said Rajendra Datta, senior director of product marketing for
Symmetricom. "With our experience, we have been producing the most
technically advanced high precision atomic clocks. Now, Symmetricom
offers a major break-through in rubidium oscillator design with the
SA.3Xm, the smallest, lightest and most economical rubidium oscillator,
making it ideal for deployment in a wide variety of mobile base
stations, transmission stations, network elements and other
communications equipment."

Atomic clocks provide enhanced accuracy, stability and timing precision
compared to quartz-based technologies. Until now, the size and power
consumption of existing atomic clock technologies have exceeded that of
quartz-based clocks, preventing the deployment of atomic technology in
a wider range of applications. The SA.3Xm is smaller than many of the
high-end quartz oscillators and matches the same pin-outs and
footprint, easing the designer's job in adopting the product.

The SA.3Xm family launches with two versions, SA.31m and SA.33m. The
SA.31m is suitable for mobile applications, such as Universal Mobile
Telecommunications System (UMTS) or Wideband Code Division Multiple
Access (WCDMA). It is an effective solution for independent timing at
base stations, as it enables the transition to cost-effective and
efficient Ethernet backhaul transport. The SA.33m is applicable for
long holdover applications, such as CDMA.

Prototypes of SA.3Xm's are available now with initial commercial
availability in November 2007. General availability is early 2008.
