Editing Clock synchronization (section)

==Terminology==
In [[serial communication]], clock synchronization can refer to [[clock recovery]], which achieves frequency synchronization, as opposed to full [[phase synchronization]]. Such clock synchronization is used in [[synchronization in telecommunications]] and [[automatic baud rate detection]].<ref>{{citation |url=http://heather.cs.ucdavis.edu/~matloff/Networks/Serial/Serial.pdf |title=Transmission on a Serial Line |access-date=2018-04-17 |author=Norman Matloff |date=September 3, 2001}}</ref>

[[Plesiochronous]] or [[isochronous]] operation refers to a system with frequency synchronization and loose constraints on phase synchronization. [[Synchronous]] operation implies a tighter synchronization based on time perhaps in addition to frequency.
