Abstract
A timing signal generation device includes: an output terminal that outputs a standard signal; a first standard signal generation unit that generates a first standard signal based on a reference signal input from outside; a second standard signal generation unit that generates a second standard signal based on a signal output from an oscillator; and a control unit that switches the standard signal output from the output terminal from the first standard signal to the second standard signal based on prior information indicating that accuracy of the reference signal deteriorates.
