The invention provides a method and device for digital filtering and de-jittering. The method includes: filtering burrs in clock input signals to generate corresponding initial clock output signals, the clock input signals including a first clock input signal and a second clock input signal; performing reverse operation on the initial clock output signals to generate a first clock output signal and a second clock output signal; and according to the level of the first clock output signal and the second clock output signal that are fed back, switching on or switching off a corresponding switch, connecting with a clock input signal that a trigger corresponds to, and filtering jitter in the first clock input signal and/or the second clock input signal. The method for digital filtering and de-jittering realizes filtering and de-jittering of the clock input signals, and can also filter the burrs generated by the input signals in a process of digital filtering. The device is simple in structure ...
