Timing ICs

5G moved from FDD to TDD to improve spectrum efficiency. That move resulted in new timing issues to keep networks in sync.

Microchip Technology announces the new TimeProvider XT Extension System, a fan-out shelf used with redundant TimeProvider 4100 grandmasters to migrate legacy BITS/SSU equipment to a modular and resilient architecture. The TimeProvider XT provides operators with a clear path to replace existing SONET/SDH frequency synchronization equipment while adding timing and phase, essential for 5G networks. As…

Network elements must meet certain frequency, phase, and time requirements to ensure proper end-to-end network operation. Synchronization architectures defined by the O-RAN alliance dictate how Open RAN equipment can meet these requirements. Open RAN continues to attract interest from service providers looking to reduce cost, improve competition, and drive technology innovation. The desire for a…

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.

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,…

Optical fiber can carry analog RF signals from antenna to receiver with far less loss than coaxial cables.

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…

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.

IEEE 1588 PTP and SyncE protocols keep radio units, switches, and distribution units in sync.

The SiT5008 from SiTime goes to 60 MHz, draws 3.5 mA, and features a standby mode.
