Abstract
An electronic device and data transmission protection device thereof are provided. The data transmission protection device includes an input clock signal detector and a control signal generator. The input clock signal detector receives a reference clock signal, and detects a frequency of an input clock signal provided by a host end according to the reference clock signal, and frequencies of the reference clock signal and the input clock signal are different. The control signal generator enables a generated control signal when the frequency of the input clock signal is larger than a safety setting value. The control signal is used to disable the host end to perform a data accessing operation on a protected circuit.
