How "input clock" and "output clock" are used in i.MX6 ASRC?

[satoshishimoda]

Hi community,

Please see Figure 15-4 in IMX6SDLRM (Rev.1).

I want to know how "Input clock X" and "Output clock X" are used in i.MX6 ASRC.

I understand "Input clock X" are used for input of Pre-processing in Figure 15-3, and "Output clock X" are used for input of Post-processing in Figure 15-3 as attached image.

Is this correct?

If my understanding is wrong, could you let me know how these clocks are used?

Best Regards,

Satoshi Shimoda

"Input clock X"  corresponds Fsin (Figure 15-3. Signal processing configurations of the i.MX6 SDL RM )

"Output clock X" corresponds Fsout.

Table 15-7 (Pre-processing, post-processing options) shows what configurations are possible when

it is needed to convert the sampling rate of a signal, associated with an input clock into a signal, associated

with a different output clock.
