CONTROL INTERFACE
permits separate record and playback
sampling rates, vital for most modern
applications. A stereo 24-bit multi-bit
sigma delta DAC with oversampling
digital interpolation filters provides
the output signal. Digital audio input
word lengths from 16-24 bits and
sampling rates from 8kHz to 192kHz
are supported.
Stereo analog-to-digital conversion
is provided by a 24-bit multi-bit sigma
delta ADC, again supporting output
word lengths from 16-24 bits and
sampling rates from 32kHz to 96kHz.
The audio data interface supports
I2S, left justified, right justified and
DSP digital audio formats.
PRODUCT BENEFITS
TARGET APPLICATIONS
