Sequence pulse falling edge jitter loading apparatus

Abstract

The invention discloses a sequence pulse falling edge jitter loading apparatus. Waveform decomposition is executed on a sequence pulse needing to load jitter to form a rising edge signal and a falling edge signal, the jitter is converted into delayed timing control, the delayed timing control is loaded to the falling edge, the rising edge signal serves as the clock of a trigger, and the falling edge signal serves as a reset signal, so that the sequence pulse signal is pulled up at the arrival of the rising edge and is pulled down at the arrival of the falling edge, and thus the waveform synthesis of the falling edge jitter loading of the part of sequence pulse signal is realized, wherein the falling edge delays under the action of a programmable delay line, and the numerical value of the delay is program-controlled, so the arrival moment of the falling edge changes with the control data, as the falling edge of the sequence pulse signal synthesized by the rising edge and the falling edge generates periodic jitter, the falling edge can load the programmable jitter r, and thus the expandability and the flexibility are very good.
