Abstract
The clock data restoration deviceis a device which restores a clock signal and data on the basis of an input digital signal and comprises an equalizer section, a sampler section, a clock generation section, an equalizer control section, and a phase monitor section. As a result of the loop processing of the equalizer section, the sampler section, and the equalizer control section, a control of a level adjustment amount of the digital signal by the equalizer sectionis carried out. However, the control is stopped by the phase monitor sectionwhen the phase difference between the clock signal CK and the digital signal is greater than a predetermined value. As a result, a clock signal and data can be restored more accurately.
