In reference to ADV7842: Hardware User Guide UG-214, section 8.31.5 (page number 239), CS_DATA[27:24] explains about the PCM sampling rate detection support.

It describes following sampling rate detection is possible 32, 44.1, 48, 88.2, 96, 176 and 192kHz.

 

We would like to know what happens if input sampling rate is 22.05 or 11.025kHz.

Is it possible to detect these sampling rates?

If not, how to find out incoming audio sampling rates are unsupported using ADV7842 registers.
