Rutronik UK adds Hong Kong X’tals’ GNSS oscillator
The K-Star global navigation satellite system (GNSS) disciplined oscillator (GNSSOD) receives signals from satellites to generate a high-precision one pulse per second output. It supports concurrent reception of signals from GPS, GLONASS, BEIDU and GALILEO and is now available from Rutronik UK. The K-Star GNSSDO is available in a form factor of 155 x 165 x 55mm.
The K-Star series GNSSDO is time and frequency synchronised to UTC and provides a low-noise 10MHz reference output. It receives GNSS signals with a sensitivity of down to -167dBm. With a long-term frequency stability that shows deviations of less than 1E-12, the K-Star achieves the quality standards of Stratum 2 of the Network Time Protocol and ITU-T Type II (G.812) of the International Telecommunication Union.
While temperature variation and aging of the core crystal impact the accuracy of traditional GNSSDOs when there is outage in GNSS-signal, Rutronik says the K-Star GNSSDO is able to learn and compensate the influence of temperature and ageing characteristics due to the AOM system modelling algorithm. The holdover performance for the one pulse per second output is better than ±1.5 microseconds accuracy over 24 hours under temperature variation of up to 20 degrees C.
Stability and holdover performance make the K-Star GNSSDO suitable for 4G and 5G LTE-TDD basestations. It can also be used in the energy industry where operators require an accurate time source to monitor the energy flow of networks and finance and stock exchanges where accurate time stamping is required to trace all transactions.
Rutronik UK operates as an independent company with a team of qualified employees with broad experience of the electronics industry.
