CHANDLER, Ariz.,
June 18, 2019
/PRNewswire/ -- The world depends on commercially available
maser atomic clock technology to deliver precise frequency and
timing for applications including metrology, deep space research
and global navigation. Microchip Technology Inc. (Nasdaq: MCHP),
via its Microsemi subsidiary, is meeting the needs of these
demanding applications with the MHM-2020, its hydrogen maser atomic
clock that improves typical long-term stability performance by
nearly 10 times over the previous generation MHM-2010. Building on
the MHM-2010's long service life and cost of ownership legacy, the
MHM-2020 offers an upgraded user experience with a color touch
panel display and secure network management port.
Hydrogen masers deliver stability by operating on the
principle that hydrogen atoms, in the proper environment, emit
microwaves at a precise 1420405751 Hertz (Hz) frequency.
Phase-locking this extremely small-power and high-purity signal to
a very high-performance quartz oscillator delivers a clock output
signal with the necessary long-term stability and phase noise to
enable precise time keeping. Active hydrogen masers are the most
advanced commercially available atomic clocks produced by
Microchip, quadrupling the stability of passive hydrogen masers
while providing superior short-term stability compared to cesium
beam tube atomic clocks.
Designed and manufactured in the U.S., the MHM-2020 maser
uses a novel drift-compensation feature to significantly improve
long-term clock-drift and aging performance, which is critical for
metrology and timekeeping applications. This builds on the legacy
of the MHM-2010, which set the industry's expectations for long
service life and low cost of ownership. Its improved performance
makes the MHM-2020 the preferred choice of national labs that work
with Bureau International des Poids et Mesures (BIPM) standards for
maintaining Coordinated Universal Time (UTC) worldwide, enabling
users to attain <3E-16/day long-term aging along with improved
temperature stability (tempco) and lower magnetic field
sensitivity. The maser's short-term clock stability performance
between 1-100 seconds range meets the stringent requirements of
Very Long Baseline Interferometry (VLBI) for radio astronomy
research such as studying black holes and other applications that
require a low noise, precise frequency and timing
reference.
"As the leading supplier of commercial atomic clock
solutions, Microchip continues to invest, develop and deliver new
capabilities to our customers," said Randy
Brudzinski, vice president and general manager of
Microchip's frequency and time business unit. "The MHM-2020 maser
builds upon the widely valued heritage of the current MHM-2010
product and we are offering an upgrade option to customers who
purchased the MHM-2010 maser during the past five years so they can
benefit from Microchip's technology advancements without having to
purchase a new system."
Pricing and Availability
The MHM-2020 76001-20X active hydrogen maser and upgrade
package for users of applicable legacy MHM-2010 masers are both
available. The maser can be specified with an optional low
phase noise packaging option. Microchip supports the maser with
clock maintenance, on-site repair and consulting services, as well
as an extended warranty.
