Any digital system relies on an accurate clock for operation. While a clock signal can be provided from room temperature into the cryogenic environment, a clock generated at low temperatures features both smaller system size and tighter integration with the remainder of the electronics. While custom integrated cryogenic oscillator architectures have been proposed, mainly for the generation of radio-frequency signals, no commercial devices have been shown to operate at temperatures as low as 4 K. In this work, we focus on cryogenic frequency generation with commercially available oscillators. Eight commercial crystal and MEMS oscillators, generating 50 or 100 MHz signals, were tested over a wide temperature range from 300 K down to 4 K. Although MEMS devices suffered from apparent ageing effects after several cooling cycles, the majority of crystal oscillators were fully functional even at such low temperatures. The oscillation frequency of crystal-based devices decreased by roughly 0.1%, while power consumption and signal amplitude were slightly higher at cryogenic temperatures. The phase noise and corresponding phase jitter were elevated mainly due to increased flicker noise; the best device shows a phase jitter increase from 350 fs at 300 K to 620 fs at 4 K.","PeriodicalId":180164,"journal":{"name":"2018 IEEE International Frequency Control Symposium (IFCS)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132120076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the measured data of propagation delay, the relationship between the propagation delay variation of the user group received signal is analyzed, the distance between the user is 100 kilometers. It is founded that when the signal transmission path is similar and the weather is similar on the path, the variation of propagation delay of the signal is basically the same with time. In view of the above analysis, a method for obtaining the high precision propagation delay is proposed, and the method is verified by the actual measurement data. The results show that the method compared with the traditional method can get high precision propagation delay and can reflect the real-time change of propagation delay. It is proved that the proposed method can further improve the timing precision of long wave system, and lay a solid foundation for the study of differential timing technology of long wave.","PeriodicalId":180164,"journal":{"name":"2018 IEEE International Frequency Control Symposium (IFCS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129798164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
