Many thanks to AD people, now I have 1452miniz board and can continue development of the assistive device for the blind. Now I am reading the board's datasheet and meet the following passage: "The AD1938 is configured to run at a sample rate of 44.1 kHz or 48 kHz. It is not possible to change this setting. Even though the ADAU1452 is very flexible and can run at any sample rate up to 192 kHz, the analog audio inputs and outputs on the EVAL-ADAU1452MINIZ may be distorted or silent if a sample rate other than 44.1 kHz or 48 kHz is used for the ADAU1452 serial ports."
So I just wanted to be sure that I know what will happen if I try to make a project for 192khz. Will nothing work?
Do I have to tweak the board? Or, the processor ticks the clock pins on the AD1938 with fixed 48Khz frequency regardless of the mode, in which AD1938 samples the incoming signal? Which means everything will work fine? Could anybody please help and clarify? I am really confused.
Thank you guyz!
