The miniature GPS Disciplined Oscillator from Brandywine Communications is a combination of a GPS receiver and a high stability oscillator. This GPSDO supplies a low noise, precision 10 MHz frequency reference signal output. This output is accurate to 1x10-12 when slaved to a GPS source.
The frequency standard is also able to slave to an external 1PPS signal to steer and hold the internal oscillator and clock system precisely in time. Time and frequency information maintains its high accuracy with the internal oscillator even when no satellites can be tracked.
The Miniature GPS Disciplined Oscillator meets military requirements such as MIL-STD-188-164A. It is available in a surface mount package that measures 2 x 2 x 1 mm. A serial data port is provided to report time, date, position, and GPS satellite health and signal strength.
