PCM3070 SLAS724 – FEBRUARY 2011 www.ti.com DAC The PCM3070 includes a stereo audio DAC supporting data rates from 8kHz to 192kHz. Each channel of the stereo audio DAC consists of a signal-processing engine with fixed processing blocks, a programmable miniDSP, a digital interpolation filter, multi-bit digital delta-sigma modulator, and an analog reconstruction filter.

PCM3070 SLAS724 – FEBRUARY 2011 www.ti.com The PCM3070 further includes programmability (Page 0, Register 27, D0) to place the DOUT line into a hi-Z (3-state) condition during all bit clocks when valid data is not being sent. By combining this capability with the ability to program at what bit clock in a frame the audio data begins, time-division multiplexing (TDM) can be accomplished, enabling the use of multiple codecs on a single audio serial data bus.
