5G or even 6G era needs more strict synchronization in a network to sustain the functionalities, especially for eMBB (enhanced mobile broadband) and URLLC (Ultra Reliability and Low Latency Communication).

IEEE-1588v2 protocol and Synchronous Ethernet are two essential solutions to deliver the clock accuracy from UTC to each Stratum level in a synchronous hierachy.

The TCXOs JTS75HC and JTS53HC perform 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.

• Compliance with ITU-T G.8262 Options 1 & 2 and Stratum 3 in GR-1244 Core & CR-253-Core.
• Free-run frequency stability of +/-4.6ppm including 20-year aging
• 24-hour holdover stability of +/-0.37ppm with temperature variation
