5.0 SAMPLE RATE CONVERTER
The sample rate converter re-samples the selected input data source in order to send to the DSP an
audio stream with a fixed frequency of 48 KHz. Figure 1 shows the basic architecture.

Figure 3: Sample Rate Converter
The threshold selector block makes the selection between a X2 Fir interpolation and direct anti-aliasing
Filter on the input data automatically. If the input sampling frequency, (measured by DRLL), is higher
than the SRC threshold (see Table 5 in section 12.9), the direct initializing filter is selected, otherwise if
the input frequency is lower than the SRC threshold, the X2 FIR filter is added to the data path. A 1kHz
hysteresis is fixed around the SRC threshold nominal values of Table 5 section 12.9, to prevent unstable
settings.
