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 new 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, the K-STAR GNSSDO is able to learn and compensate the influence of temperature and aging characteristics thanks to the advanced AOM system modeling algorithm. As a result, the holdover performance for the 1PPS output is better than ±1.5μs accuracy over 24 hours under temperature variation of up to 20°C.
With its excellent stability and holdover performance the K-STAR GNSSDO is suited for 4G and 5G LTE-TDD base stations. Other applications include energy industry where energy operators require an accurate time source to monitor the energy flow of their networks and finance and stock exchanges where accurate time stamping is required to trace all transactions.
