Abstract
A clock data recovery unit includes: a phase corrector generating a first compensation clock signal and a second compensation clock signal based on an external clock signal; and a transition detector, wherein the transition detector comprises: a first integrator configured to integrate a first training pattern signal according to the first compensation clock signal to provide a first integration signal; and a second integrator configured to integrate the first training pattern signal according to the second compensation clock signal to provide a second integration signal, wherein, in response to the first integration signal being greater than a first reference voltage and the second integration signal being less than the first reference voltage, occurrence of a transition of the first training pattern signal is detected.
