Master clock select
Table 9.
The STA339BWS supports sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz,
176.4 kHz, and 192 kHz. Therefore the internal clock is:
The external clock frequency provided to the XTI pin must be a multiple of the input sample
frequency (f
The relationship between the input clock and the input sample rate is determined by both
the MCSx and the IR (input rate) register bits. The MCSx bits determine the PLL factor
generating the internal clock and the IR bit determines the oversampling ratio used
internally.
