Microchip Technology has announced the release of its new portfolio of GNSS Disciplined Oscillator (GNSSDO) modules, aimed at simplifying the integration of Position, Navigation and Timing (PNT) technology in aerospace and defense systems. The company’s latest modules incorporate Microchip’s embedded atomic clock and oscillator technologies, such as the Chip-Scale Atomic Clock (CSAC), Miniature Atomic Clock (MAC), and Oven-Controlled Quartz Crystal Oscillators (OCXOs).
The GNSSDO modules process signals from Global Navigation Satellite Systems (GNSS) or alternative clock sources to discipline onboard oscillators. This provides precise timing, stability, and holdover performance for applications including radar, satellite communications, military radios, vehicle platforms, and environments where GNSS signals may be denied.
Among the newly introduced products is the MD-013 ULTRA CLEAN module, which supports multiple GNSS constellations—GPS, Galileo, BeiDou, NavIC—or an external reference input. Built around a high-performance OCXO, it offers ultra-low phase noise and strong short-term frequency stability. Outputs include 1 PPS TTL, 10 MHz sine wave, and 10 MHz square wave signals disciplined by a 72-channel single-band GNSS receiver with upgrade options for dual-band support.
The MD-300 module targets harsh environments with a compact footprint and features either a MEMS OCXO or TCXO as its local oscillator. It is designed for low g-sensitivity and tolerance to shock and vibration, making it suitable for drones and portable equipment. The LM-010 module is intended for Low Earth Orbit applications that require radiation tolerance alongside stable timing.
“Microchip’s expertise in PNT systems is instrumental in helping our customers seamlessly integrate these GNSSDO modules into their designs,” said Randy Brudzinski, corporate vice president of Microchip’s frequency and time systems business unit. “Our products can be adjusted to meet the specific requirements of each application, whether it is through a custom solution or incremental changes to the standard product. We provide an end-to-end solution to streamline the development process.”
The modules use a common serial communication protocol and graphical user interface for configuration. Parameters such as inputs, outputs, auto switching, holdover settings, GNSS tracking data, and reporting messages can be set through this software.
Microchip offers other solutions for aerospace and defense sectors—including Radiation-Tolerant microcontrollers (MCUs), FPGAs, Ethernet PHYs, power devices, RF products, timing solutions—as well as components available on Qualified Products Lists (QPL). The company serves more than 100,000 customers across several markets including industrial automation and automotive manufacturing through its comprehensive product portfolio. More information about Microchip’s offerings can be found at www.microchip.com.
Development tools supporting the GNSSDO line include VDOM3 software with a GUI for tuning module parameters during system integration testing. An evaluation kit is also available for monitoring performance of certain models.
The new GNSSDO modules are now available in production quantities through Microchip sales representatives or authorized distributors.
