Linux-based clock management software offer PTP synchronization for 4G, 5G, and Open RAN

Renesas Electronics Corporation introduced PTP (Precision Time Protocol) Clock Manager, the industry’s first Linux-based clock management software, providing an easy-to-use and accessible timing synchronization solution for telecom networks, including 4G, 5G, and open radio access network (O-RAN), including both front haul 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 synchronization without the need for time-intensive customization. This timestamp 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.

The new Linux-based PTP Clock Manager also works with Renesas’ 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: Extremely effective packet delay variation (PDV) filter for IEEE 1588 networks; Linux kernel PHC subsystem supports Renesas ClockMatrix timing devices; Backwards compatibility with Linux v3.0 or later; Reduces the impact of packet-delayed variations caused by random queuing delays; Enables worldwide compliance with ITU-T synchronization recommendations; Available as clear source code to simplify debugging

As the market leader in silicon timing, Renesas offers the only “one-stop-shop” for timing solutions, offering expertise and products from full-featured system solutions to simple clock building-block devices. The new PTP clock manager extends this comprehensive portfolio to include both silicon and software solutions to support a full range of clocking needs.

The Linux-based PTP Clock Manager is available now free of charge under license.
