摘要： This application relates to methods and apparatus for transfer of multiple digital data streams, especially of digital audio data over a single communications link such as a single wire. The application describes audio interface circuitry comprising a pulse-length-modulator, PLM (103). The PLM is responsive to a plurality of data streams (PDM-R, PDM-L) of audio data samples at a sample rate, to generate a stream of data pulses (MPDM) at the sample rate. The length of each said data pulse is dependent upon on a combination of the then current audio data samples from the plurality of data streams. Circuitry for receiving and extracting the data is also disclosed. An interface (104) receives the stream of data pulses (MPDM) and data extraction circuitry (105, 106) determines the pulse length of said data pulse and determines a data value for each of the plurality of audio data streams.

摘要： This application relates to methods and apparatus for transfer of multiple digital data streams, especially of digital audio data over a single communications link such as a single wire. The application describes audio interface circuitry comprising a pulse- length-modulation(PLM) modulator (204). The PLM is responsive to a plurality of data streams (PDM-R, PDM-L), to generate a seriesof data pulses (PLM)with a single data pulse having a rising and falling edge in each of a plurality of transfer periods defined by a first clock signal (TCLK). The timing of the rising and falling edgeof each data pulse is dependent upon on a combination of the then current data samples from the plurality of data streams. The duration and position of the data pulse in the transfer window in effect defines a data symbol encoding the data. Circuitry for receiving and extracting the data is also disclosed. An interface receives the stream of data pulses (PLM) and data extraction circuitry (202) samplesthe data pulseto determine which of the possible data symbols the pulse representsand determines a data value for at least one received data stream.
