TAS5825MEVM: Crossstalk tested value is not as good as the specification

Amy Luo

Part Number: TAS5825MEVM

Hi team,

One of our customers uses TAS5825MEVM, not PPCMB, but their own board's I2S and USB to I2C module. Connect I2S and I2C to the I2S and I2C interfaces of the EVM and use commands to control the EVM board to operate.
Configured with the same parameters as the datasheet, but the tested crossstalk was not as good as the datasheet.
Here are the results of the powered 24V, configured output 1W, Hybrid Modulation, FSW = 384 kHz, Load = 6 Ω, BTL Mode.

Is there any other configuration that needs attention?

Best Regards,

Amy Luo

Hi Amy

Does customer side have the Mother Board, I'm afraid that i2s signal been input to amplifier is not stable so that the result become high.

thanks.

Hi Jesse,

Yes, the PPCMB board ordered by the customer has arrived, but the measured value is about the same, please help to see if there is a problem with the customer's setup?
