Abstract

The paper proposes a principle of constructing an automatic digital synchronizer of digital or bit data stream from the primary reference oscillator of frequency generating equipment of telecommunication network without the transfer of synchronizing signals from the network reference oscillator. This principle can be used in optical transport networks (OTN), cable channels and in 5G radio relay networks (10–100 Gbit/s). Automatic digital synchronizer enables us to receive asynchronous signals in synchronous mode (RS 232C, CAN) maintaining the synchronous operation of computer or telecommunication network with complete elimination of wander and significant reduction of jitter.
