  • Patent number: 9965435
    Abstract: Aspects disclosed in the detailed description include communicating low-speed and high-speed parallel bit streams over a high-speed serial bus. In one aspect, a data transmitting circuit converts a low-speed parallel bit stream into a high-speed parallel bit stream and then serializes the converted high-speed parallel bit stream based on a high-speed reference frequency. In another aspect, a data receiving circuit recovers the low-speed parallel bit stream from the high-speed parallel bit stream if the low-speed parallel bit stream is determined to exist in the high-speed parallel bit stream.
    Type: Grant
