Renesas Electronics Corporation has introduced an IEEE 1588 PTP (Precision Time Protocol) Clock Manager, the industry’s first Linux-based clock management software that provides easy-to-use and accessible timing synchronization for telecom networks, including 4G, 5G, and open radio access network (O-RAN), including both fronthaul and backhaul systems.
The new IEEE 1588 Renesas PTP Clock Manager includes APIs to connect timing ICs from Renesas with any network processor via the Linux standard PTP stack, offering broad access to PTP synchronization without the need for time-intensive customization. This time stamp unit (TSU)-agnostic approach provides customers access to their processor/clock combination of choice and eliminates the need to create their own APIs, allowing them greater design flexibility while reducing development costs. When used with clock products from Renesas, the PTP Clock Manager is provided under a “no fees” license.
“Timing precision becomes more critical as carriers migrate to 5G networks. The open-source Linux environment offers the flexibility to create IEEE 1588-aware systems with a TSU and clock combination of choice for optimum timing performance,” said Bobby Matinpour, Vice President, Data Center Business Division at Renesas. “Providing PTP synchronization alongside a suite of best-in-class timing solutions without license fees reshapes the network system development landscape.”
“We are collaborating closely with Renesas to develop joint reference designs that help to simplify and accelerate the time to market for our customers,” said Gilles Garcia, Senior Director of Marketing, Wired and Wireless Group, Xilinx, Inc. “5G networks demand high accuracy 1588 PTP for time and phase synchronization. Renesas’ PTP Clock Manager is an important enabler for our Versal AI Core Series VCK190 and Zynq UltraScale+ RFSoC ZCU216 evaluation kits, along with Xilinx Ethernet.”
The new Linux-based PTP Clock Manager also works with the ClockMatrix™ 8A3400x family of high-performance, precision, multi-channel timing devices and IEEE 1588-compliant 82P339xx devices to simplify the integration of telecom PTP solutions.
Key features of the PTP Clock Manager include an extremely effective packet delay variation (PDV) filter for IEEE 1588 networks; backwards compatibility with Linux v3.0 or later; worldwide compliance with ITU-T synchronization recommendations; and a Linux kernel PHC subsystem that supports Renesas’ ClockMatrix timing devices.
The clock manager reduces the impact of packet-delayed variations caused by random queuing delays and is available as clear source code to simplify debugging.
The Linux-based PTP Clock Manager is available now free of charge under license.
