Re: USB
With true asynchronous transmission the DAC is remarkably immune to jitter because a buffer in the DAC controls the flow of the data. The DAC controls the audio transfer from the computer, ignoring the computers USB bus clock and instead slaving the computer to the buffer in the DAC. The DAC requests the packets of audio data from the computer and stores this data in the buffer. The DACs buffer and the digital converter chip itself are then syncd with a single fixed-frequency clock. This method assures a irtually jitter-free transmission.
