Completely Digital, synthesizable and technology independent DACs for audio/video
The Stereo Sigma-Delta DAC is a digital converter core suitable for high quality multimedia applications. The DAC accepts a stereo digital input signal at a standard rate up to 48 kHz and produces a stereo analog output. Each channel has a volume control and several muting options programmed through a parallel control bus. A digital roll-off equalizer is provided to compensate for the droop introduced by the reconstruction filter.
The input clock frequency needs to be 512 X the audio sample rate.
The DAC produces an audio clock to sample the input audio signals.
The design is fully digital and requires only a small number of passive external components for the reconstruction filter.
