Abstract
The disclosure provides a signal synchronizing device and a digital signal output device. A digital circuit counts a first frequency signal to generate a count value, and generates an output voltage according to the count value. An analog circuit generates a feedback signal according to the output voltage. A synchronization circuit samples the feedback signal according to a second frequency signal to generate a synchronization signal. A control circuit generates a voltage control signal according to the second frequency signal and the synchronization signal to control the digital circuit to stop counting the first frequency signal, and a frequency of the first frequency signal is lower than a frequency of the second frequency signal.
