ABSTRACT:
A method for recovering a position and clock period from an input bi-phase encoded digital signal such as an SPDIF signal counts the intervals between phase changes of the input digital signal to derive the longest interval between the phase changes. The longest interval indicates the position and period length of a preamble portion of sub-frames of the signal and is stored, and a signal indicating the position of the longest interval between phase changes and an indication of the clock period of the input digital signal is provided.
