Space-qualified ultra low phase noise master crystal oscillator
The LNMO builds on the success of the model MO master crystal oscillator by offering the lowest noise performance in a very low profile, lightweight package for advanced satellite applications. Its ultra-low noise option features -110 dBc/Hz at 1 Hz from the 10 MHz carrier. Environmentally robust and designed with high reliability and long lifecycle, its hardened radiation rates less than 100 kRad.
It also extends the limits of several other key performance characteristics, including an ultra small profile and footprint of 50 x 50 x 30 mm, lightweight package coming in at 100 g, low power consumption of 1.5 W nominal and fast warm-up time of 10 minutes. The device has high frequency stability over a wide temperature range of ±1E-9 over -30 °C to +70 °C) and low aging of ±1E-10/day. Long-term stability is ±1E-8/year, while short-term stability is 1E-12 from 0.1 to 10 s.
According to Pascal Rochat, Founder and Managing Director of Spectratime, "Many space applications benefit from small size and light weight factors, but equally from ultra low phase noise of a crystal oscillator. Navigation systems, including GNSS receivers, up/down converters, transponders, board calculators, synthesizers and more, require a clock signal with ultra low phase noise performance. The LNMO was specifically designed to meet those needs where atomic clocks are unpractical".
