A jitter monitor includes: a voltage generating circuit configured to generate a first voltage that is varied with time at a predetermined inclination; a voltage reducing circuit configured to reduce the first voltage by a predetermined voltage in synchronization with a first clock signal so as to generate a second voltage that is varied with time at the predetermined inclination in synchronization with the first clock signal; and a sampling circuit configured to sample a portion having the predetermined inclination of the second voltage. |
