RSGGO10T3G GPS-Guided Reference Oscillator

RSGGO10T3G GPS-guided reference oscillator is ideally suited for mobile equipment and wherever it is important to have a frequency reference which can be turned off when not in use yet be precisely on frequency within a few minutes.  It gives 100ppb stability locked to a 1 pulse per second (1pps) signal from an integrated GPS receiver.  A combination of novel circuits, special firmware algorithms, conformal-coating, and patented nanotechnology provide a low-current miniature unit with very high performance at an attractive price. 

The RSGGO10T3G reaches its specified accuracy of better than 5 x 10E10 within two minutes after GPS lock. The standard module frequency is 10MHz, but other frequencies are available on request. 

The RSGGO10T3G modules provide extremely low phase noise with none of the phase discontinuity or jumps of other solutions and is highly immune to drops in GPS signal, missing 1pps pulses or pulse distortions caused by fading or other influences. Unpredictable jitter of the 1pps signal does not have a negative effect on the short- or long-term stability of the system.  Missing GPS pulses do not lead to an immediate loss of accuracy.   Since the GPS signal is NIST traceable, RSGGO10T3G modules do not need calibration.   

Two of the unit’s pins can be used as an I2C interface for optional control or programming, or to drive a two-color LED to indicate internal status (red = no GPS; amber = locking; green = locked to spec.)   A test board with (RS-TBGGO) and without (RS-TBGGO-NG) GPS receiver is also available.
