Microchip’s GNSS-disciplined oscillator (GNSSDO) modules combine positioning, navigation, and timing (PNT) for mission-critical aerospace and protection purposes. Constructed with the corporate’s chip-scale atomic clock, miniature atomic clock, and OCXOs, the compact modules are well-suited for techniques that function in GNSS-denied environments.
The modules course of reference alerts from a GNSS or an alternate clock supply to self-discipline the onboard oscillator, making certain exact timing, stability, and holdover operation. They’ll perform as a PNT subsystem inside a bigger system or as a stand-alone unit.
All modules output 1-PPS TTL and 10-MHz sine wave alerts, with distinct options for various use instances:
- MD-013 ULTRA CLEAN – Highest-performance design with multi-constellation GNSS help, ultra-low section noise, and short-term stability; non-obligatory dual-band receiver upgrades.
- MD-300 – Rugged 1.5×2.5-in. module with MEMS OCXO or TCXO for low g-sensitivity, shock/vibration tolerance, and low thermal response; fitted to drones and manpacks.
- LM-010 – PPS-disciplined module for LEO requiring radiation tolerance, stability, and holdover; constructed with a digitally corrected OCXO or low-power CSAC.
The GNSSDO modules can be found in manufacturing portions.
