The Basics of Synchronized Ethernet-SyncE
With Ethernet having become the dominant technology for data transmission, Synchronous Ethernet (SyncE) is now used to synchronize networks in the physical layer in a fashion similar to SONET/SDH or T1/E1. Originally published in EETimes Asia in 2009, Microsemi applications engineer Slobodan Milijevic describes the basics of SyncE and how telecom providers can confidently implement networks based on SyncE as a cost-effective and reliable solution.
使用现成的信号源作为抖动/漂移发生器
