The IP has stereo digital-to-analog output systems including interpolation, multibit D/A conversion
and output analog filtering . The IP supports major audio data interface formats. Individual devices differ only in the supported interface format.
The IP is based on a fourth-order multibit delta-sigma modulator with a linear analog low-pass filter. This IP also includes autospeed mode detection using both sample rate and master clock ratio as a
method of auto-selecting sampling rates between 2 kHz and 200 kHz.
The IP contains on-chip digital deempha-sis, operates from a single +3.3 V or +5 V power supply,and requires minimal support circuitry. These features are ideal for DVD players & recorders, digital televisions, home theater and set top box products, and automotive audio systems.
