TAS5760LD: How to reduce the noise caused by jitter

Part Number: TAS5760LD

Hi Team,

Please help me answer the follow question, thank you so much.

Jitter is occurred in the “I2S_SCLK”. It was found that noise is generated in the audio signal due to this jitter. Is there a setting that can reduce the effect of jitter on the IC side?

Connect “I2S_SCLK” of Bluetooth module and “MCLK” of TAS5760LDAP via 22Ω resistor.

Connect “I2S_SCLK” of Bluetooth module and “SCLK” of TAS5760LDAP via 22Ω resistor.

Connect “I2S_SDOUT” of Bluetooth module and “SDIN” of TAS5760LDAP via 22Ω resistor.

 Currently, we are in the final stage of prototyping and can not add the circuit of Clock jitter cleaner. Is there a setting that can improve the noise just by changing the setting of I2C?

Best Regards,

Tom.Liu
