(VC)TCXO Stratum 3 Clipped Sine

JTSxxCS-Serie is a (voltage controlled) temperature-compensated crystal oscillator with sophisticated features to meet the requirement for the reference clock of Stratum 3. Its comprehensive compensation technique can guarantee very tight stability over a wide range of operating temperatures. The short- and long-term aging is well controlled to only allow a total +/-4.6ppm frequency excursion with all defined environmental variations and up to 20-year duration. The clipped sinewave (VC)TCXOs supplied by 1.8V up to 3.3V in a 3225 package are compliant with ITU-T G.8262 Options 1 & 2 and Stratum 3 GR-1244 Core & CR-253-Core. It is dedicated well to synchronous Ethernet equipment clocks (EECs) and Optical-Transport-Network equipment clocks (OECs).

5G and the next generation 6G when launched require strict synchronization within the telecommunication network to sustain the functionalities, especially for eMBB (enhances mobile broadband) and URLLC (Ultra Reliability and Low Latency Communication).

IEE-1588v2 protocol and Synchronous Ethernet are two key solutions to deliver the clock accuracy from UTC (Universal Time Coordinated) to each Stratum level in a synchronous hierarchy.  JTSxxCS performs a compliant holdover capability, ±0.37ppm over 24 hours, allowing the clock integrity to be maintained for at least as long as the Stratum 3 standard clock requires when the timing signal of master sources are not available.

 Ethernet are two essential solutions to deliver the clock accuracy from UTC to each Stratum level in a synchronous hierachy.

JTSxxCS performs a compliant holdover capability letting the clock integrity be kept up for at least as long as the Stratum 3 standard clock when the timing signal of master sources absents.
