(54) УСТРОЙСТВО ГРУППОВОЙ ТАКТОВОЙ СИНХРОНИЗАЦИИ(54) GROUP TACT SYNCHRONIZATION DEVICE

Изобретение относитс к дискретным системам св зи и может использоватьс дл тактовой синхронизации групповой аппаратуры преобразовани сигналов, примен е ой в технике передачи дискретных сигналоаThe invention relates to discrete communication systems and can be used for clock synchronization of a group of equipment for signal conversion, used in the technique of transmitting discrete signals.

Известно устройство групповой тактовой синхронизации, содержащее п канальных делителей, входы которых соединены с опорным генератором, также фазовый дискриминатор и обнаружитель перерывов св зи (Ij.A device for group clock synchronization is known, comprising p channel divisors, the inputs of which are connected to a reference generator, also a phase discriminator and a communication break detector (Ij.

Однако это устройство достаточно сложное .However, this device is quite complicated.

Целью изобретени вл етс упрощение устройства путем исключени (п- 1) фазовых дискрилсинаторов.The aim of the invention is to simplify the device by eliminating (p-1) phase discrinsors.

Устройство групповой тактовой синхронизации работает следующим образом.The device group clock synchronization works as follows.

Claims

An input discrete signal is supplied to one of the inputs of the phase discriminator 3 through the signal switch 5. The other input of the phase discriminator 3 through the switch 6 clock pulses receives clock pulses from the output of the channel divider 1 of the same channel, whose input signal at this time point arrives at the first input of the phase discriminator 3. The phase correction pulses ("add or exclude) from the output phase discriminator 3 through the switch 7. correction pulses are fed to the input of the channel divider 1 of the same channel. After a predetermined synchronization time has elapsed, using switching pulses from the output of the reference generator 2 to the switch 5 signals, the switch 6 clock pulses, the switch 7 correction pulses, the signal and clock pulses of the next channel synchronously switch to the corresponding inputs of the phase discriminator 3, and t Also, the correction signals from the output of the phase discriminator 3 to the input of the channel divider 1 of the next channel. After performing these switching operations, the adjustment is carried out in a similar way. Single-phase clock of the next channel on the receiving member corresponding channel. Calculations of the proposed device showed that with the number of channels less than 30, one and a half to two is required. times less cost, expressed in the IC package, and, therefore, in power consumption.
