I'm quite confused between time synchronization and clock synchronization.
Self-clocking signal is used to tell the receiver at which rate sender sending the bits so that it can read the bits at the same rate (to avoid data loss).
Precision Time Protocol is a protocol used to synchronize clocks throughout a computer network. On a local area network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems.
are both doing the same job here? is Self-clocking signal still needed even if the network perfectly synced by PTP mechanism?
