PROBLEM TO BE SOLVED: To suppress power consumption by maintaining a synchronous relation between LRCLK and BCLK while using a low-frequency system clock.SOLUTION: A clock generating device comprises first clock generating means which generates a first clock from a system clock, second clock generating means which generates a second clock of a higher frequency than a frequency of the first clock from the system clock, count means which counts the number of second clocks included within a term of the first clock, and adjustment means which adjusts a falling edge or a rising edge of the second clock to be synchronized with a falling edge or a rising edge of the first clock based on an assert signal which is outputted when a count value obtained by the count means becomes a predetermined value. |
