Hi Expert,
We are getting a problem with this hardware control IC and getting too much distortion over audio because of format mismatch, we have pulled down the FMT pin using a 100 Ohm resistor to get a 24-bit I2S format. From the laptop, we have selected 24-bit 44.1 kHz format. At scope, the waveform of LRCK and BCK, we get the right frequencies 44.1 KHz and 2.822 MHz respectively as per the datasheet.
Previously, we were using PCM1753-Q1, we had configured SPI from software to set format 24-bit 44.1 kHz and successfully play audio without distortion.
Please correct me if I am doing the wrong configuration.
Thanks,
Mohit
