Implementing Precision Frequency Measurement (PFM) Using a DPLL to Improve Time Synchronization

Learn how to implement frequency stabilization using Precision Frequency Measurement (PFM) and Digital Phase-Locked Loop (DPLL) in this technical presentation from Skyworks' Product Line Manager. Explore how Precision Time Measurement (PTM) enables time synchronization over PCI Express within datacenters, particularly crucial for virtualized 5G RAN and distributed AI applications. Discover the benefits of PFM implementation, including enhanced time synchronization and reduced local oscillator stability requirements, allowing for the use of more cost-effective temperature compensated crystal oscillators (TCXOs) instead of expensive oven-controlled crystal oscillators (OCXOs) in high-end applications.
