IEEE 1588 is a precise time protocol (PTP) used to synchronize clocks in computer networks. In a local area network, it can control the clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems. With 5G becoming more available throughout the world, there are a large number of base stations and IoT devices which require a large-scale network synchronization. Renesas advanced clock recovery algorithms and precision timing devices reconstruct accurate synchronization signals for 5G networks. And, the CL8040 Wi-Fi 6 device enables wireless configuration of IEEE 1588.

System Benefits​:

  • IEEE 1588 solution realized with Renesas' high-processing performance MPU and precision timing clock IC.
  • Dual MAC, dual PHY and dual lane PCIe 3.0
  • Flexible architecture implies one chip operation as 5GHz + 2.4GHz with 4T4R MIMO system




  • Core and access IP switches/routers
  • Synchronous Ethernet equipment
  • Wireless infrastructure for 5G network equipment
  • 10Gb, 40Gb and 100Gb Ethernet interfaces
