  • Patent number: 7872498
    Abstract: In some embodiments, a chip includes transmitters to transmit differential signals on conductors; and current mode circuitry to selectively modulate a common mode voltage of the differential signals to communicate data. In other embodiments, a system includes a first chip to transmit first and second differential signals on conductors, and a second chip. The second chip includes receivers to receive the first and second differential signals from the conductors and provide received signals representative thereof, and current mode circuitry to selectively modulate a common mode voltage of either the first or second differential signals to communicate data and wherein the first chip includes common mode detection circuitry to detect changes in the common mode voltage. Other embodiments are described and claimed.

  • Patent number: 7088398
    Abstract: A communication system including a transmitter, a receiver, and a serial link, in which encoded data (e.g., video, audio, and optionally also other auxiliary data) are transmitted from the transmitter to the receiver. The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels of the link during data islands between bursts of encoded video data, a pixel clock is transmitted over the link, and the receiver regenerates a clock for the audio data using time code data in the packets and the pixel clock. Other aspects of the invention are transmitters for transmitting encoded data and a pixel clock over a serial link, receivers for receiving such data and pixel clock and performing audio clock regeneration, and methods for transmitting encoded data and a pixel clock over a serial link and performing clock regeneration using the transmitted data and pixel clock.
