5G Timing Solutions

Mobile network architectures have been drastically impacted by the need for higher speeds, higher bandwidth and lower latency in this new era of global connectivity. 5G technology is rapidly emerging to address these needs and to provide reliable, robust and high-quality services to end users around the world. The connectivity, speed and performance unleashed by this leading-edge technology is driving advances in hand-held mobile devices, autonomous vehicles, smart cities, smart homes and an array of Internet of Things (IoT) applications.

These next-generation 5G networks require highly accurate synchronization to enable end-to-end nodes to meet the extremely tight time accuracy requirement of ±130 ns. While 4G networks relied on GPS receivers at every cell site to act as time sources, 5G networks use the IEEE® 1588 Precision Time Protocol (PTP) as the primary method to synchronize time across devices. Our portfolio of synchronization products has the performance and features you need for implementing accurate time performance in your leading-edge 5G designs.

Key Features

  • Precise phase/frequency measurement and tuning features to lower system latency to achieve Class C and, in the future, Class D performance
  • Field-proven and sophisticated packet clock recovery algorithms that are the most widely deployed by carriers
  • Small-form-factor OCXO and TCXO with superior slope vs. temperature performance and operating temperature range up to 105°C
  • Very-low-noise VCXO/XO to support 5G jitter requirements
  • OCXOs with temperature stability of less than 3 ppb and superb holdover performance including 1.5 ms

Key Applications

  • Central timing function for carrier network equipment compliant to ITU-T G.8262.1, G.8273.2 and G.8273.4
  • Communications systems timed by any combination of Synchronous Ethernet, IEEE 1588 PTP or GPS/GNSS
  • Support for new 5G wireless architectures: CU, DU and RU systems
  • 5G systems with precise time requirements driven by advanced services such as carrier aggregation, coordinated multipoint, OTDOA location, etc.
