The MD-175 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 or CMOS 10 MHz, and HCMOS 1 pps output. An onboard precision OCXO provides stabilities in the unlocked mode enabling extremely low holdover. The module operates from -40°C to +85°C.
