TAS5548: I2S Input Word Length

Sadanori Kato

Part Number: TAS5548

Hi,

How does TAS5548 work if inputting 32bits audio data although TAS5548 supports up to 24bits for I2S input word length ?
Is my understanding correct that lower 12bits of audio data is cut off ?

Best regards,

Kato-San,

As per the datasheet: "The TAS5548 masks unused trailing data bit positions." This means that any bits in excess of the maximum 24 I2S bits accepted will be masked (ignored).
