MD-178

In Production

The MD-178 is a Microchip GNSS disciplined module. It is a fully integrated GNSS disciplined oscillator module in a compact surface mount 40 x 50 mm footprint. The module has an embedded 72 channel receiver that is GPS, GLONASS and Galileo compatible and provides a sinewave 10 MHz RF output, and HCMOS 1 pps output. An onboard Low Noise OCXO provides a Low Phase Noise RF output. The module operates from -40°C to +85°C.
