5G’s high speeds place extreme demands on the components that maintain accurate time. Compliance with industry timing standards calls for accuracy in the face of temperature changes, shock, and vibration.
Synchronizer keeps 5G networks on time
The Zyntai network time synchronizer from Net Insight picks up where precision-time servers leave off. Without timing and synchronization, networks would simply not run; data would never arrive at its destination. That’s where network timing products come in. At MWC 2023, Swedish network equipment vendor Net Insight will demonstrate Zyntai Time Node and Zyntai Director,…
RF over fiber: overcoming an inherent transmission-line problem, part 1
Optical fiber can carry analog RF signals from antenna to receiver with far less loss than coaxial cables.
ICs and software synchronize Open RAN networks
The Si55xx and Si540x timing ICs from Skyworks work in tandem with AccuTime software to provide low-jitter clocks and IEEE 1588 PTP fronthaul sync. In networks, timing is everything. Without solid, accurate timing and synchronization, data gets lost. Skyworks has introduced ICs that work with its software to address the timing relative to 5G radios…
Synchronizing 5G networks brings timing challenges
Frequency synchronization in the radio access network (RAN) minimizes disturbances at the air interface, ensures mobile handover between radio base stations, and fulfills legal and regulatory requirements associated with a frequency license.
How timing design and management synchronizes 5G networks
The infrastructure needed to deliver cost effective, reliable, and secure timing throughout cellular networks needs proper architecture, design, and management. Tighter time accuracy demands for 5G networking equipment requires reliable and robust timing architectures that guarantee network performance.
Oscillator shrinks size and power
The Elite X Super-TCXO from SiTime provides stable timing from 1 MHz to 60 MHz for edge computing, vehicles, and cellular base stations.
Timing IC combines functions for Open RAN
Microchip’s ZL30735 integrates eight DPLLs, five low-output jitter synthesizers, and an IEEE 1588-2008 protocol stack. The splitting of radio access network functions creates an Open RAN that promises greater innovation and features in 5G networks. Splitting the traditional baseband unit into radio units (RU), distribution units (DU) and centralized units (CU) brings timing issues not…
How timing sources synchronize open RAN networks
IEEE 1588 PTP and SyncE protocols keep radio units, switches, and distribution units in sync.
Renesas adds three timing ICs for 4G/5G radios
The 8V19N850 radio synchronizer and 8V19N880/8V19N882 jitter attenuators enhance a radio unit’s timing capabilities.
