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 sub-microsecond ranges, making it suitable for measurement and control systems. This optimized IEEE 1588 solution uses a dual-core Arm® Cortex®-A55 (1.2GHz) CPU and 9-Channel power management IC (PMIC) supporting DDR memory to achieve high performance, high efficiency and a smaller PCB size.

System Benefits​:

  • IEEE 1588 solution realized with Renesas' high-processing performance MPU and precision timing clock IC.
  • Renesas advanced clock recovery algorithms reconstruct accurate synchronization signals for networks.
  • The clock accuracy is within ±10ns.
  • Highly accurate AC/DC and PMIC provide a complete power solution.

Target Applications:

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