ABSTRACT:
A phase synchronizing apparatus that operates with a low power consumption so as to be particularly suited for use in battery powered data communications situations. The phase synchronizing apparatus receives reception data containing a data code portion synchronous with a transmission clock of a predetermined frequency and produces a reception clock synchronous with the transmission clock. The phase synchronizing apparatus uses a synchronization counter and a compensation circuit to achieve the phase synchronization. The invention can also be implemented as a decoder for decoding data received from a data transmission or as an integrated circuit for data communication.
