Abstract
The present invention discloses a phase interpolating apparatus comprising: a first signal generation circuit, configured for generating a first signal having a first phase; an optional second signal generation circuit, configured for generating a second signal having the first phase; a third signal generation circuit, configured for generating a third signal having a second phase; a fourth/fifth signal generation circuit, configured for generating a fourth signal having a third phase when operating in a first mode and for generating a fifth signal having the second phase instead of the fourth signal when operating in a second mode; and a phase interpolator, configured for generating an interpolated signal without utilizing the fourth signal when operating in the first mode and for generating the interpolated signal according to the first signal, the third signal, and the fifth signal when operating in the second mode.
