Microsemi Corporation, a wholly owned subsidiary of Microchip Technology Inc. (Nasdaq: MCHP), today announced the launch of its SA.45s Commercial Space Chip Scale Atomic Clock (CSAC), the industry’s first commercially available radiation-tolerant CSAC.
Ideally suited for low Earth orbit (LEO) applications, the device provides the accuracy and stability of atomic clock technology while achieving significant breakthroughs in reduced size, weight and power (SWaP) consumption.
As the newest member of Microsemi’s CSAC product family, the Commercial Space CSAC provides excellent drift performance and built-in 1 pulse per second (PPS) input for GPS disciplining, making the device well-suited for holdover applications. It is targeted at several other commercial space and space research applications, including:
- satellite timing and frequency control;
- satellite cross linking;
- assured position, navigation and timing; and
- Earth observation.
With many spacecraft manufacturers turning to commercial off-the-shelf (COTS) parts to meet performance, schedule and cost requirements, the Commercial Space CSAC offers a solution for many satellite missions.
“With the introduction of the Commercial Space CSAC, we now offer a space-deployable atomic precision clock reference with radiation tolerance in support of the space market’s desire to reduce mission costs and design times using COTS devices,” said Peter Cash, director of the clock business unit at Microsemi. “As the first atomic reference clock with low SWaP available for space, our new device is well-suited to applications requiring precise clock synchronization, including a variety of existing and emerging LEO applications.”

According to a market intelligence report by Euroconsult titled, “Satellites to be Built & Launched by 2026 World Market Survey,” the total revenue for satellite manufacture and launch is expected to be $304 billion between 2017-2026. With revenues of $102 billion, LEO is expected to account for a third of the total market, with 82 percent derived from satellite manufacturing.
“Harris provides the world’s most advanced sensors, payloads and communications technologies; receiving and information processing systems; and analytics which provide our customers with the integrated information and actionable intelligence they need for mission and business success,” said Tim Lynch, general manager, Mission Solutions at Harris Corporation’s Space and Intelligence Systems segment (NYSE: HRS). “Microsemi’s latest atomic clock will support Harris in delivering complete mission solutions to our customers.”
As a stand-alone atomic clock with a 10 megahertz (MHz) CMOS-compatible output, Microsemi’s Commercial Space CSAC is a timing module providing an impressive short-term stability (Allan Deviation) and frequency stability across the operating temperature (TempCo). A standard CMOS-level RS-232 serial interface is built into the device, which is used to control and calibrate the unit and provide a comprehensive set of status monitors. The interface is also used to set and read the CSAC’s precise internal time-of-day clock. Microsemi’s radiation-tolerant ruggedized oscillators also include OCXOs and state-of-the art EMXOs for applications that require higher accuracy and can support higher power consumption.

Other key features include:
Power consumption of less than 120 milliwatts (mW)
Less than 17 cubic centimeters volume (1.6″ × 1.39″ × 0.45″)
Radiation-tolerant: 20 krad
Single event latch-up (SEL) and single event upset (SEU) tested to 64 megaelectron-volts per square centimeter/milligram (Mev-cm2/mg)
Short-term stability (Allan Deviation) of 3.0 × 10–10 at TAU = 1 sec
Frequency stability across temperature range (TempCo) less than 5×10-10
1PPS output and 1PPS input for synchronization and time-keeping
RS-232 interface for monitoring and control

Microsemi Leading Space Innovation for More than Half a Century
With one of the industry’s most comprehensive portfolios of space products, Microsemi provides radiation-tolerant field programmable gate arrays (FPGAs), radiation-hardened mixed-signal integrated circuits (ICs), radiation-hardened DC-to-DC converters, precision time and frequency solutions, linear and POL hybrids, custom hybrid solutions, and radiation-hardened discretes including the broadest portfolio of JANS Class diodes and bipolar products. Microsemi is committed to supporting its products throughout the lifetime of its customer programs.
The company continues to innovate and expand its portfolio, most recently adding its new LX7730 radiation-tolerant telemetry controller IC providing key functions for sensor monitoring, attitude and payload control, as well as its RTG4™ high-speed signal processing radiation-tolerant FPGA family. The RTG4’s reprogrammable flash technology offers complete immunity to radiation-induced configuration upsets in the harshest radiation environments, requiring no configuration scrubbing, unlike SRAM FPGA technology.
