Abstract
The present disclosure provides an auto-determining sampling frequency method. The method is for determining sampling frequency for an input signal of a single wire transmission interface. Each frame of the input signal includes a preamble and binary data presented in a plurality of bits. The method includes utilizing an internal sampling clock to acquire a plurality of period widths of the preamble and the binary data in the input signal and determining range of the sampling frequency according to the detected period widths of the preamble and the binary data.
