Claim 14:
15. The quadrant alternate switching phase interpolator of claim 14, wherein the synchronous circuit comprises:
a third multiplexer circuit configured to output one of the first clock signal and the second clock signal to be the first synchronous signal according to a first switching signal;
a fourth multiplexer circuit configured to output one of the third clock signal and the fourth clock signal to be the second synchronous signal according to a second switching signal;
a first latch circuit configured to output the first bit and the third bit to the first multiplexer circuit according to the first synchronous signal, wherein the first synchronous signal is inputted to an inverting input terminal of the first latch circuit; and
a second latch circuit configured to output the second bit and the fourth bit to the second multiplexer circuit according to the second synchronous signal, wherein the second synchronous signal is inputted to an inverting input terminal of the second latch circuit.
