The invention discloses a silencing vibration stopper and an adjusting method thereof, and belongs to the technical field of vibration control. The silencing vibration stopper comprises a belleville spring set, a spring oscillator unit, a lead screw adjusting mechanism and a frequency modulation control system; the spring oscillator unit comprises a top plate, a spring oscillator and a bottom plate. The belleville spring set is arranged between the spring oscillator and a first supporting column set and a second supporting column set between the spring oscillator and the top plate and the bottom plate in a sleeving mode. The lead screw adjusting mechanism comprises an adjusting lead screw, and the adjusting lead screw can penetrate through the top plate and the spring vibrator and then is connected with the middle connecting column. The spring oscillator unit is provided with an acceleration sensor group; the frequency modulation control system collects vibration signals in real time through the acceleration sensor set, the lead screw adjusting mechanism is driven through a PID control algorithm, the pre-tightening force of the belleville spring set is dynamically adjusted, and the vibration absorption frequency is adjusted. Dynamic adjustment of the inherent frequency can be achieved, the structure is convenient and fast, the adjustment precision is high, the response speed is high, and the requirement for narrow-frequency-domain vibration suppression is met.

The application provides a clock shift circuit, a serializer, a deserializer and an electronic device. An input end of a delay unit is used for connecting an analog sampling clock. Output ends of the delay unit are respectively connected with control ends of a first shift unit and a second shift unit and a control end of a decision device. The output ends of the delay unit are also used for connecting a digital sending module. An input end of the first shift unit is used for connecting a first reference clock. An input end of the second shift unit is used for connecting a second reference clock. An output end of the first shift unit is connected with a first input end of the decision device. An output end of the second shift unit is connected with a second input end of the decision device. An output end of the decision device is connected with the control end of the delay unit. Even if the timing relationship is changed due to the changes of the temperature and voltage in the chip during the data transmission process, the timing relationship between the analog sampling clock and the data sending clock can be adjusted in real time, so that the data can be correctly sampled.
