Renesas looks to simplify 5G networks with first IEEE 1588 synchronisation software

1 min read

Renesas has introduced the PTP (Precision Time Protocol) Clock Manager, the industry’s first Linux-based clock management software.

It has been designed to provide an easy-to-use and accessible timing synchronisation solution 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 Renesas timing ICs with any network processor via the Linux standard PTP stack, offering broad access to PTP synchronisation without the need for time-intensive customisation.

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 Renesas clock solutions, 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 synchronisation alongside a suite of best-in-class timing solutions without license fees reshapes the network system development landscape. We are excited to continue driving innovation that fosters and enables new vendors to succeed, consistent with initiatives like O-RAN.”

“We are collaborating closely with Renesas to develop joint reference designs that help to simplify and accelerate the time to market for our customers,” added Gilles Garcia, Senior Director of Marketing, Wired and Wireless Group, Xilinx. “5G networks demand high accuracy 1588 PTP for time and phase synchronisation.

"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 Solutions.”
