PCM1754-Q1: Output waveform is not proper and noise observed while playing sound

Hi,

We are using PCM1754-Q1 for audio application. 

Circuit Details:

iMX8 (SAI) --> PCM1754-Q1 --> TAS5411 --> Speaker

PCM1754 is configured as follows:

Fs = 24 kHz

BCLK = 768 kHz

SCK = 18.432 MHz

Input Sound Source:

Sample Rate = 24 kHz, Duration = 500 ms, Repeated infinitely

Speaker Output:

We found 2 issues when the sound is playing

1) Speaker output is not exactly same as input

2) Noise observed during play

We have checked the I2S data and it is exactly matched with input.

Could you please support us to resolve the above issues?

Thanks and Regards,

Viswanath
