MD-261

In Production

The MD–261 is a fully integrated GNSS disciplined oscillator module in a compact surface mount 25 x 20 mm package. The module has an embedded 34 channel receiver that is both GPS and GLONASS compatible. and provides an LVCMOS 10 MHz and 1 pps output. An onboard OCXO or High Precision TCXO is available dependent on performance requirements. The module operates from −40°C to +85°C, and is capable of providing a holdover of 1.5 µs over 2 hours over a ±2°C temperature window. An evaluation kit with operating software is available for development purposes....
