A skew-tolerant digital phase detector is provided. Specifically, a detector is provided in the digital phase detector to detect certain failure conditions that may result from clock skew and duty cycle distortion. If the condition is detected, an adjusted signal is generated and the adjusted signal is synchronized with the reference signal. By using the generated signal to provide a lock if certain conditions arise, adjustment errors resulting from duty cycle distortion and clock skew can be minimized.
