TAS5760M-Q1: TAS5760 output signal

Part Number: TAS5760M-Q1
Other Parts Discussed in Thread: TAS5760M

Hi Team,

  1. customer want to have 12kHz output signal on TAS5760. As you see attached picture from customer, they can’t make 12KHz LRCK value. Can you give me an advice how to set the 12kHz LRCK value?

  2. What kind of condition can make clock error? And, What does meaning of below two condition?
  3. - 1. Non-Supported MCLK to LRCK and/or SCLK to LRCK Ratio

    - 2. Non-Supported MCLK or LRCK rate

  • Hi Kim,

    we are looking into this issue, Shawn Zhen will get back to you soon later.

  • Hi Kim,

    See my comments below.

    a) customer want to have 12kHz output signal on TAS5760. As you see attached picture from customer, they can’t make 12KHz LRCK value. Can you give me an advice how to set the 12kHz LRCK value?

    [Andy]: As the Table 6 in the TAS5760M datasheet show, MCLK has to be 512 * 12kHz = 6.144MHz and SCLK can be 3.84MHz (32*12kHz), 5.76MHz (48*12kHz) or 7.68MHz(64 * 12kHz).

    b) What kind of condition can make clock error? And, What does meaning of below two condition?

    1. Non-Supported MCLK to LRCK and/or SCLK to LRCK Ratio

    2. Non-Supported MCLK or LRCK rate

    [Andy]:  As I mentioned above,  the SCLK to LRCLK ratio has to be 32, 48 or 64 for 12kHz sample rate. If other ratios is detected, a clock error occurs.

    Likewise, if an non-supported LRCLK (12kHz, 16kHz, 24kHz, 32kHz, 38kHz, 44.1kHz, 48kHz, 88.2kHz or 96kHz) is detected, a clock also occurs.

  • Hi Anthony,
    Could you please help to close this question if it's anwered? Thank you!
