    hello,

    TAS5825 support TDM4. as it only have 2 channels output, does it mean your system will use 2 TAS5825 device?
    SAP_CTRL2 Register can config corresponding audio data shift.

    How many channels are TAS5825M TDM?

    If the TDM of TAS5825M is not 4-channel, can it support the TDM of 4-channel input?

    How many channels does the TDM of TAS5825M have?


    With TDM input, if the input is a 4-channel TDM TAS5825, can it be supported?


    My current application is:

    Through the DSP tuning, set EQ, and then through 4 channels of TDM input to 4 TAS5825M

    When one of the TAS5825M receives a modified EQ from the DSP, the TAS5825M changes, while the others remain unchanged.

    hello,

    TAS5825M can support TDM8. TDM4 is also supported.

    do you use host DSP to config EQ and send by Data to control differnet channel different DSP coeffcient setting?

    1. TAS5825M supports several channels of TDM, can 16 channels support it?

    2. Is there any reference schematic diagram using TDM input as the application mode?

    3. Can the following registers distinguish the receiving data

    hello,

    for your questions:

    1. TAS5825M supports several channels of TDM, can 16 channels support it?
    [A] see SAP_CTRL2 register, max I2S shift LSB is 512SCLKS. so it can support 16CH.
    2. Is there any reference schematic diagram using TDM input as the application mode?
    [A] no specific reference design for TDM input
    3. Can the following registers distinguish the receiving data
    [A] yes, you can config SAP_CTRL2 register different value to set different I2S shift to give different TDM slot different TDM data. for exmaple, for TDM1, you can configure offset=32SCLKS, TDM2 offset=64SCLKs.
