Abstract:Future ultra-broadband and low-latency radio access networks pose stringent specifications for time synchronizations. For 5G base stations, inter-site timing error should be <;span style="font-size: 11.25px;"><; <;/span>130ns for carrier aggregation and <; 10ns for high-accuracy positioning [1], requiring a 10-10-level relative drift for a 1min clock holdover. Meanwhile, massive deployments of compact access nodes also make small size, power, and cost indispensable for clocks. Oven-controlled crystal/MEMS oscillators (OCXO/OCMO) with moderate cost are currently used. But, their resonators exhi
