What is a Chip Scale Atomic Clock?
CSAC was a program initiated by DARPA
Goal was to create an atomic clock 100X smaller and 100X less
power consumption than existing technologies
Such a product would be an enabling technology for handheld,
autonomous sensor, and secure comms applications
Symmetricom was a technology leader in the program
from the start
First compliant physics package
First autonomous clock
Symmetricom made the decision
to commercialize CSAC and
accelerate development with its own investment

CSAC Performance =
Breakthrough Benefits
Accuracy and stability to meet the most
demanding applications <<0.1 sec error over a human lifespan
Extremely low power consumption 1/40th or less the power consumption of existing
atomic oscillators.
Tremendous reduction in battery size, cost, and weight.
Extends product deployments
Small size, reduced weight 1/8th the volume, 1/7th the weight of
traditional atomic oscillators.
Enables truly portable applications.

Principles of ANY Atomic Clock
Atomic resonance is intrinsically more stable than quartz local
oscillator.
“Natural” atomic microwave resonance frequency is synthesized
from RF LO.
Control Loop continuously steers LO frequency to atomic
resonance.
RF output (typically 10 MHz) embodies stability of atomic
resonance.

Applications
Applications which benefit
from CSAC
Require precise time for synchronization
without direct connection
Require ability to hold precise time even
in absence of GPS
Need to minimize size, weight, and
power (SWaP)
Examples include:
Portable “man-pack” equipment for
the military
Distributed geophysical sensors,
underground or underwater
PAGE 13© COPYRIGHT SYMMETRICOM (2010)Rev.11-2010
Portable Military Applications
Example
Dismounted (Backpack) Jammers
Problem: Need to jam wireless signals used to detonate
Improvised Explosive Devices (IEDs)
First jammers were vehicle-mounted, but ~70%
of all patrols in Afghanistan are on foot.
Dismounted jammers must be synchronized to
allow friendly communications, while blocking
detonation signals.
Solution: CSAC precision enables synchronization, while
its low power consumption reduces the amount
of batteries needed to power the jammer.

Marine Applications
Example
Acoustic pulse hits & penetrates
ocean floor.
Sound travels thru different materials
at different speeds.
Sensors time-stamp when pulse
is received.
Post-processing shows likely places
for oil or natural gas.
Problem: How to keep sensors synchronized in absence of GPS.
How to prolong the time sensors can stay underwater.
Solution: CSAC provides 100x stability improvement compared to current solutions.
CSAC achieves this while consuming 10 to 20% of the power of current solution.
