Problem of TAS5706A MCLK

Hi, Jian,

It looks like maybe you are tripping the thermal protection.

Try reducing the input amplitude, gain, or increasing the load impedance, and I think you will see it work better.

Hi, Don ,

As your advise,I try to reduce TAS5706A input amplitude(1Vrms to 600mVrms), gain(0db to -5db,individual channel),and increasing load impedance(8ohm to 24ohm).But I found output signal of power amplifier is still discontinuous.Also, I found that  the power amplifier is in the state of "Frame slip"  by reading the value of 0x02 of register.I produced LRCLK,SCLK by TAS5706EVM2  and MCLK by external other crystal (12.288MHZ,the same frequency with crystal of TAS5706EVM2) in my design. Does it affect output signal?

Hi, Jian,

Are you sure? Even though it's for a different device, the sticky bit info is the same - please review this post: http://e2e.ti.com/support/amplifiers/audio_amplifiers/f/6/p/197635/704617.aspx#704617

Hi,Don,

I'm not sure whether I mislead you. SCLK,LRCLK and MCLK is not produced by the same clock source in my design.SCLK,LRCLK is produced by a crystal and MCLK is produced by the other.But the two crystal are the same frequecy (12.288MHZ). Does it affect " frame slip" and output signal?
