  Back to Product Table


The MD–171 is a Extended Holdover GNSS disciplined module. It is a fully integrated GNSS disciplined oscillator module in a compact surface mount 40 x 50mm footprint. The module has an embedded 34 channel receiver that is both GPS and GLONASS compatible and provides a sinewave or CMOS 10MHz, and HCMOS 1pps output. An onboard precision OCXO provides stabilities in the unlocked mode enabling extremely low holdover. The module operates from −40°C to +85°C.
