PROBLEM TO BE SOLVED: To provide a timing signal generating circuit that generates a high speed timing signal with high accuracy, and has a wide operating frequency range with a simple configuration and also generates the timing signal of small jitter. SOLUTION: The timing signal generating circuit is provided with a 1st timing signal generating means 1 that receives a clock CKr and generates a 1st timing signal CKs by providing a delay effectively variable to the clock CKr, a phase control means 2 that controls a phase of a 1st timing signal CKA from the 1st timing signal generating means 1, and a 2nd timing signal generating means 3 that frequency-divides the 1st timing signal CKA to produce a 2nd timing signal CKin with a frequency being one over an integer of the frequency of the 1st timing signal CKA. |
