Skyworks releases timing solutions for 5G

Skyworks Solutions, Inc. has unveiled its new portfolio of timing and network synchronization solutions for 5G NR and O-RAN fronthaul networks. These include the Si551x and Si540x families of NetSync clock IC devices and AccuTime IEEE 1588 software.

Accurate time synchronization is critical to ultra-reliable network operation and is paving the way for future advances, including ultra-reliable low-latency communications (URLLC) and coordinated multipoint access (CoMP) for 5G to support emerging applications like autonomous vehicles, factory automation, and telemedicine, said Skyworks.

The Si551x and Si540x timing solutions comply with relevant telecom standards, including ITU-T G.826x/G.827x, IEEE 1588-2008/2019, and O-RAN WG4.

The new Si551x devices, consisting of the Si5518 and the Si5512 low-phase-noise-jitter network synchronizer clocks, combine the functions of network synchronization, jitter attenuation, and JESD204B/C clocking in a single device. Both devices incorporate Skyworks’ fifth-generation ultra-low-jitter DSPLL architecture with MultiSynch ‘any frequency’ clock synthesis, which allows multiple clock and synchronization functions to be combined in a single device. This results in lower power consumption and board space savings.

The Si540x series is optimized for equipment in the fronthaul network, such as distribution units and fronthaul switches and gateways. The Si5401, Si5402 and Si5403 network synchronizer clocks with DSPLL provide network synchronization and synchronous Ethernet/SDH clock wander filtering.

The new AccuTime IEEE 1588 software, compatible with the Si551x and Si540x products, is designed to deliver a complete IEEE 1588 software implementation and flexible precision time protocol (PTP) solution. The software supports time recovery performance to meet the requirements of fronthaul network deployments using full (FTS), partial (PTS) or assisted partial (APTS) timing support.

The Si551x and Si540x timing solutions are in production. Samples and evaluation kits (Si55xx-A-EVB and Si540x-A-EVB) are available now.
