Abstract
A signal processing device includes an oscillation circuit, a protection target circuit, a delay time detection circuit, and a clock control circuit. The oscillation circuit receives the frequency control signal and generates a clock signal having a frequency corresponding to the frequency control signal. According to the above-mentioned configuration, even when a delay failure due to aging occurs in the signal processing device, it is possible to prevent a malfunction.
