Microsemi Corporation has announced its new thermally improved chip-scale atomic clock (CSAC) components with full operating and storage temperature. The new devices offer low-power holdover atomic clock technology without compromising size, weight and power (SWaP) while operating at a wide temperature range. Microsemi is exhibiting this week at ION GNSS+, being held in Portland, Oregon. With an operating temperature range of -10 to 70 degrees Celsius, Microsemi’s new CSAC components are highly reliable, with improved product design, process enhancements and robust product verification/validation, the company said. The revolutionary technology enables new applications and missions not possible in the past with traditional OCXO and Rubidium clocks, offering the low SWaP clock technology at 17 cubic centimeters (cc) in size, 35 grams of weight and only 120 milliwatts of power. Microsemi’s CSAC product offers ±5.0E-11 accuracy at shipment and a typical ≤ 9.0E-10/month aging rate, which makes it suitable for many low-power atomic clock holdover applications. “The enhancements to our CSAC product offering focus on providing the highest reliability without compromising performance for our customers, particularly in mission critical applications where every milliwatt matters,” said Ramki Ramakrishnan, director of product line management, at Microsemi. “These devices utilize an innovative approach to the component level atomic clock that will help Microsemi access the entire oscillator industry, along with miniature atomic clocks (MAC), and capitalize on the revenue growth potential within the defense, communications, industrial and test and measurement markets.” According to the “Crystal Oscillator Market—Global Forecast & Analysts” report posted by Markets & Markets, the total available market (TAM) for the overall oscillator market is estimated to be $2.4 billion in 2016, with OCXO markets targeted by CSAC estimated to have a serviceable addressable market (SAM) of $260 million in 2016. Microsemi’s thermally improved CSAC products support the company’s strategic presence in the defense and security markets, targeting applications such as low-power holdover against GPS vulnerabilities for position, navigation and timing security. They are also suitable for holdover in underwater (ocean bottom nodal) applications and atomic frequency reference in test and measurement applications. “Leveraging the unique attributes of Microsemi’s CSAC technology, our company is able to offer an unprecedented combination of holdover, g-sensitivity, low power consumption and warm-up performance, while reducing the footprint to less than the critical 0.6 inches height — allowing retrofitting of legacy equipment,” explained Said Jackson, president of Jackson Labs Technologies, Inc. “The CSAC combined with our battle- and theater-proven software algorithms and support hardware enables vastly extended mission times while providing critical backup performance for GPS-denied environments when even the optional integrated Selective Availability Anti-spoofing Module (SAASM) GPS technology is jammed.” Microsemi’s thermally remediated CSAC components are sampling now, with full production in October.
