DEVICE FOR SYNCHRONIZING A CLOCK SIGNAL AND SYNCHRONOUS DATA TRANSMISSION SYSTEM COMPRISING SUCH A DEVICE |
摘要 |
A device for the synchronization of a local timing signal which restores the baud rhythm at which the binary data of a message are received comprises a device for making the frequency and phase of the local timing signal dependent on the transitions of the data signal received and a rapid synchronization circuit for accelerating the synchronization process. This circuit counts the number of coincidences of n successive transitions detected (n equals a positive integer) with each of k separate time intervals (k equals positive integer) of the same duration. It divides up the integrality of each cycle of the local timing signal and supplies a pulse as from the time at which p coincidences with one of the k intervals of time have been counted. This pulse makes it possible to initiate the dependent local timing signal within a very short time. |
