Showing the Effect of a Programmed Data Word Offset
The TLV320AIC31 supports the following standard audio sampling rates: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz,
22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz. The converters can also operate at
different sampling rates in various combinations, which are described further below.
The data converters are based on the concept of an FSref rate that is used internal to the part, and it is related to
the actual sampling rates of the converters through a series of ratios. For typical sampling rates, FSref will be
either 44.1 kHz or 48 kHz, although it can realistically be set over a wider range of rates up to 53 kHz, with
additional restrictions applying if the PLL is used. This concept is used to set the sampling rates of the ADC and
DAC, and also to enable high quality playback of low sampling rate data, without high frequency audible noise
being generated.
The sampling rate of the ADC and DAC can be set to FSref / NDAC or 2 × FSref / NDAC, with NDAC being 1, 1.5,
2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, or 6.
