摘要： One embodiment of the invention is directed to a switchable plug comprising a first incoming line configured to carry a signal from a source device, a second incoming line configured to carry a signal from the source device, a Mic Bias output line, a Ground output line, and a switch control. The switch control is operably connected with the first incoming line, the second incoming line, the Mic Bias output line and the Ground output line. The switch control is configured to detect a type of the signal carried on the first incoming line and a type of the signal carried on the second incoming line, from the source device. The switch control is further configured to automatically route a Mic Bias type signal to the Mic Bias output line and a Ground type signal to the Ground output line, without user intervention.

摘要： A digital audio interface protocol carries multiple channels of digital audio information serially between a transmitting digital audio tape recorder and a plurality of receiving recording units. Using a three stage process, the circuitry of the present invention allows the receiving VCO's to "lock on" to the sampling rate of the serial digital data stream without any explicit sampling information. In a first stage, the VCO frequency is adjusted until a sync pattern is properly received. In a second stage, the VCO frequency is adjusted to oscillate a preselected number of times between sync pattern occurrences. In a third stage, the VCO phase is adjusted to match the phase of the serial data stream.
