    摘要： A clock data recovery circuit includes a phase-locked loop configured to generate a plurality of clock signals having unequal phases relative to each other, in response to a received clock signal, and a phase interpolator configured to interpolate phases of the plurality of clock signals during generation of multiphase sampling clock signals. A sampling clock adjustment circuit is also provided, which is configured to generate a plurality of data symbols by sampling a received data signal at sampling time points of the multiphase sampling clock signals, and further configured to: detect, from the plurality of data symbols, a first data pattern set to have a transition point immediately before a first reference data symbol, and a second data pattern set to have a transition point immediately after a second reference data symbol, detect a first signal level of the first data pattern at a sampling time point for sampling the first reference data symbol, detect a second signal level of the second data pattern at a sampling time point for sampling the second reference data symbol, and adjust phases of the multiphase sampling clock signals according to a result of comparing the first signal level to the second signal level.

    摘要： According to an embodiment, an IPL sterilization device includes a lamp configured to output light including a visible light region to sterilize a region including a surface of an object; a capacitor configured to transmit a voltage charged to the lamp; and a controller configured to control the capacitor, wherein the controller is configured to: control the lamp to be driven in an outputable state or an unoutputable state, change the lamp to the unoutputable state when the object satisfies an object overheat condition in the outputable state, and change the lamp to the outputable state when the object unsatifies the object overheat condition after the lamp satisfies the object overheat condition and changes the lamp to the unoutputable state, wherein the outputable state is a state in which the lamp is capable of outputting light by applying a driving pulse to the lamp by the capacitor, and the unoutputable state is a state in which the lamp is not capable of outputting light because the capacitor does not output a driving voltage to the lamp.
