Insights
The launch of Microchip's next-generation SA65-LN Low-Noise Chip-Scale Atomic Clock marks a strategic advancement in the $4.5 billion precision timing market. This innovation addresses critical challenges in aerospace and defense applications, where the convergence of precision timing and miniaturization is becoming increasingly vital.
The technical specifications are particularly impressive from a market perspective. The device's sub-½ inch profile represents a significant reduction in form factor while maintaining power consumption under 295mW. This combination of size and efficiency creates a compelling value proposition for military communications, radar systems and autonomous platforms where every millimeter and milliwatt counts.
What's particularly noteworthy is the integration of Microchip's proprietary EMXO technology, which effectively combines two traditionally separate components into one solution. This integration not only reduces system complexity but also provides potential cost advantages for customers, strengthening Microchip's competitive position in the high-margin defense sector.
The expanded temperature range (-40°C to +80°C) and improved stability metrics open new application possibilities in extreme environments, potentially expanding Microchip's addressable market. The low frequency drift performance of <0.9 ppb/month and minimal temperature-induced errors of <±0.3ppb are particularly valuable for unmanned systems and autonomous operations where frequent calibration isn't feasible.
This product launch reinforces Microchip's strategic focus on high-value, specialized solutions for the aerospace and defense sector, which typically offers higher margins and more stable long-term contracts compared to consumer electronics. The timing of this release aligns well with increasing defense modernization initiatives globally, particularly in areas like electronic warfare and autonomous systems where precise timing is critical.
The Low-Noise Chip-Scale Atomic Clock, model SA65-LN, enables frequency mixing for battery-powered devices
CHANDLER, Ariz., Jan. 27, 2025 (GLOBE NEWSWIRE) -- Developers need ultra-clean timing devices for aerospace and defense applications where size, weight, and power (SWaP) constraints are critical. A Chip-Scale Atomic Clock (CSAC) is an essential reference for these systems, providing the necessary precise and stable timing where traditional atomic clocks are too large or power-hungry and where other satellite-based references may be compromised. Microchip Technology (Nasdaq: MCHP) today announces its second generation Low-Noise Chip-Scale Atomic Clock (LN-CSAC), model SA65-LN, in a lower profile height and designed to operate in a wider temperature range, enabling low phase noise and atomic clock stability in demanding conditions.
Microchip has developed its own Evacuated Miniature Crystal Oscillator (EMXO) technology and integrated it into a CSAC, enabling the model SA65-LN to offer a reduced profile height of less than ½ inch, while maintaining a power consumption of <295 mW. The new design is optimal for aerospace and defense mission-critical applications such as mobile radar, dismounted radios, dismounted IED jamming systems, autonomous sensor networks and unmanned vehicles due to its compact size, low power consumption and high precision. Operating within a wider temperature range of -40°C to +80°C, the new LN-CSAC is designed to maintain its frequency and phase stability in extreme conditions for enhanced reliability.
"A significant advancement in frequency technology, our next generation LN-CSAC provides exceptional stability and precision in a remarkably compact form," said Randy Brudzinski, corporate vice president of Microchip’s frequency and time systems business unit. "This device enables our customers to achieve superior signal clarity and atomic-level accuracy, while also benefiting from reduced design complexity and lower power consumption.”
The LN-CSAC combines the benefits of a crystal oscillator and an atomic clock in a single compact device. The EMXO offers low-phase noise at 10 Hz < -120 dBc/Hz and Allan Deviation (ADEV) stability <1E-11 at a 1-second averaging time. The atomic clock provides initial accuracy of ±0.5 ppb, low frequency drift performance of <0.9 ppb/mo, and maximum temperature-induced errors of < ±0.3ppb. Together, the LN-CSAC can save board space, design time and overall power consumption compared to designs that feature two oscillators.
The crystal signal purity and low-phase noise of LN-CSAC are designed to ensure high-quality signal integrity, which is essential for frequency mixing. The atomic-level accuracy allows for longer intervals between calibrations, which can help extend mission durations and potentially reduce maintenance requirements.
