TAS5717: TAS5717 problem

Zhonghui Xu

Part Number: TAS5717

Hi team,

We use TAS5717 to drive 2 pcs 1watt&8ohm speakers with 5V PVDD supply.(schematic is shown on the attachment)

21_Audio AMP.pdf
Now we have a situation here that there is no sound out.
Signals can be measured on I2S,which follow register configuration and seems OK.
MCLK=11.28Mhz
LRCLK=44.1Khz
SCLK=2.82Mhz
Signals measured on OUT_A/B/C/D is square wave with 352khz frequency.
Register 0x1B has been set to 0X00 but still no sound out.

Is there anything wrong with my design?
What else I should check?

Thanks!

Hi Zhonghui,

Did you change the master volume register 0x07? The default for master volume is mute. That could be why you aren't seeing any output signal.

Best Regards,

Hi Robert,

Thank you for your reply.

We configure the register of 0x07 as 0x00b4.

Current problems:

1. Can you provide a set of register reference configuration list that only uses speaker?

2. No matter how we modify the parameter value of the register, The output waveforms of out_A/B/C/D are the same (a standard square wave with 352khz frequency and 5V peak), which may be caused by the wrong configuration?

Thanks again.

Best regards,

Hi Zhonghui,

Can you send me your register settings? I think it would be easier for me to test your configurations first to make sure that I see the same issues.

Best Regards,

Robert Clifton

Hi Robert,

This is our register configuration, please check, thank you!

There are still a few questions, please help to confirm.

1. Does TAS5717 have power on timing requirements? How to set the power on between PvdD, AVDD/DVDD, PDN and RESET.

2. We don't use the Headphone in our design. Is it OK for the pins (Pin1, 2, 3, 4, 47, 48) to be suspended? HP_SD need to be controlled?

Hi Zhonghui,

Thank you for sharing. Please allow us a couple of days to investigate this. We will let you know if we find anything from the script.

Best Regards,

Hi Zhonghui,

What are the other two questions?

Also I apologize, it's taking a little longer to get everything setup to test your script. Thank you for your patience.

Best Regards,

Hi Robert,

I've added them to the original question, now write them again, please check.Thanks.

Hi Zhonghui,

I'm sorry I missed them! Allow me to answer them.

1. For the power up sequence. Please look at Figure 4 on page 13 of the datasheet.

2. For the headphone pins, if you are not going to be using the headphone driver you can configure the pins as so:

Head-phone inputs & outputs can be tied to GND or left floating
HPVSS can be tied directly to GND
Cap between CPP & CPN can be removed. CPP can either be floating or tied to 3.3V. CPN can either be floating or tied to GND.
HP-shut down can be tied to GND directly

Hi Zhonghui,

What's interesting is from what I've seen through your code, you never had the master volume defined. Now this is a little confusing since you did mention register 0x07 is set to 0x00b4.

I've been manually going through the script line at a time and I haven't had any issues. I did notice that you are making changes to register 0x6A which is a reserved register. Not sure if that's the reason you aren't able to get audio passing through but I'm curious as to why you are trying to change that register.

I haven't taken a look at the bq changes you did on the registers. Can you run the script without making the bq changes and see if that works?

Thank you,

Robert Clifton
