TAS5548: USB to 6.1 CH

[FAE] Andrew Wang

Part Number: TAS5548


Hi Team,

Customer is checking if TAS5548 can do 6.1CH output with USB or miniDP input?

I would like to double confirm if my understanding is correct, TAS5548 was designed only for Blu-ray lossless audio format, therefore not suitable for USB type application, right?

Thanks.

Andrew

    Andrew,

    The TAS5548 does not care what the application is, it can handle the 6.1 audio. It does not have USB input. You can use something like a TAS1020 or XMOS device to translate the USB audio to I2S which the TAS5548 can then use.

    Regards,

    Hi Adam,

    This is where I get confused about.
    TAS5548 input takes I2S (not TDM), but I thought I2S only containing LR channel only, how TAS1020 can output 6.1 audio to TAS5548?
    Could you explain a little more detail?
    Just the concept is fine.
    Thanks.

    Andrew,

    The TAS5548 has 4 SDIN connections which each support L and R channels for 8 channels total.

    The TAS5548 EVM only has connection to SDIN1 through the TAS1020. You could solder in SDIN2, 3, and 4 but the EVM doesn't support this well.

    Internally the TAS5548 can route SDIN1 to all 8 channels for evaluation if needed.

    Regards,
