IEEE 1588 software combined with leading timing silicon delivers increased flexibility and excellent packet delay variation

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.”
