Business Wire
Symmetricom®, Inc. (NASDAQ: SYMM), a worldwide leader in
precision time and frequency technologies, today announced general
availability of the world’s smallest, lowest power atomic
oscillator. The company’s newly-released SA.45s Chip Scale Atomic
Clock (CSAC) provides the accuracy and stability of atomic clock
technology while delivering dramatic improvements in size, weight
and power. The newest member of Symmetricom’s QUANTUM™ family of
atomic oscillators is exceptionally well-suited for portable
applications requiring precise synchronization and time keeping in
GPS-denied environments. Its accuracy and extremely low power
consumption enable the SA.45s CSAC to satisfy a number of demanding
portable applications, such as dismounted IED jammers; unmanned
aerial vehicles (UAVs); next-generation man-pack radios, and
military handheld GPS units as well as geophysical sensors. The
CSAC product is available in standard and military
temperature-range configurations.
Symmetricom’s SA.45s CSAC incorporates several technology
breakthroughs that offer significant benefits for portable
applications. It is only 16cc in volume, weighs only 35 grams,
requires only 115mW of power, and provides time accuracy two orders
of magnitude better than the higher-power quartz-based solutions it
replaces, such as Oven-Controlled Crystal Oscillators (OCXOs) and
Temperature Compensated Crystal Oscillators (TCXOs).
“Our new SA.45s CSAC product brings ultra high-precision and low
power consumption to a variety of portable and underwater
exploration applications,” said Dan Scharre, executive vice
president and general manager at Symmetricom. “These applications
can’t rely on continuously receiving GPS signals, and until now,
traditional quartz-based timing options have forced users to choose
between size, accuracy, and power consumption, even while providing
less-accurate timing. We leveraged Symmetricom’s extensive history
and expertise in providing state-of-the-art timing systems and
devices to broadly deliver the first CSAC product to market and to
deliver to end-users the best performance in the smallest package
at lowest power consumption.”
The advanced technology benefits of Symmetricom’s QUANTUM™
SA.45s Chip Scale Atomic Clock have already been validated by early
adopters. Makers of underwater sensors have used the CSAC’s low
power consumption and increased stability to greatly increase
mission duration. Users who rely on military GPS systems have found
that the CSAC has the stability to maintain synchronization even
during long GPS outages, and that it also enables rapid signal
reacquisition. And of course, its small size and extremely low
power consumption allow them to get these benefits even in manpack
systems.
Availability
The QUANTUM™ SA.45s Chip Scale Atomic Clock (CSAC) is available
in two versions.
- Option 001, which operates from -10°C
to +70°C for commercial applications
- Option 002, which operates from -40°C
to +85°C for military applications
The SA.45s CSAC is available now at a U.S. list price starting
at $1,500 in small quantities.
