TAS5548: Question about mixing function for TAS5548

Hi Team,

Can you help to double check if we can achieve below mixing function for TAS5548? Also, where we can apply the TAS5548 EVM for evaluation purpose?

Thanks.

Hi Jacky

Yes there's mixer function as your picture shows.

Seems the EVM is kind of shortage, I'll double check about it.

Hi Shadow,

Do you have the EVM in your hand and can help to provide one example register configuration to achieve this mixing function for TAS5548?

Thanks.

Hi Jacky

Sorry we also don't have board for such old devices. But the function setting should be no problem. As below table shows, for each input mixer, we could set the coefficient for each input signal, and the final mixer output will be the add up of all the input signal multiply it's coefficient. The register has total 32 Byte, every 4 Byte is for one coefficient. To calculate the coefficient value into register value, we could check chapter 7.4.10.2 for information.

I checked the EVM, for this device, the board already stops production for very long time. But we could apply for TAS5634 EVM through below link, which has TAS5548/58 on the board.
