Confirm accuracy of input frequency to AIC3254

Guru 19585 points

Hi community member,

Please let me confirm the following question.


Does this device(AIC3254) has a limitation of input frequency accuracy?

i.e. Would you please teach me the rule of  input frequency in detail?

* I know that the maximum frequency was described in SLAA408 as "Maximum TLV320AIC3254 Clock Frequencies".


Now, customer used  the signal which was generated by USB OSC block in DSP.

They would like to change this signal to use the signal which is generated by crystal(12MHz).

So, they would like to know whether the signal has a limitation to use.

If you have any questions, please let me know.

Best regard.
