Abstract: A signal receiving apparatus and method adapted for receiving a MIPI signal are disclosed. The signal receiving apparatus includes a signal receiver, a selector, a decoding apparatus and a byte boundary searcher. The signal receiver receives a clock signal, and obtains an input data stream according to the clock signal. The selector outputs the input data stream to a first or second output terminal according to a decoding error signal. The byte boundary searcher operates a boundary searching operation on the input data stream for generating a byte tuning information, wherein, the signal receiver adjusts the clock according to the byte tuning information for adjusting the input data stream.
