TAS2563: How to get started

Zoe Ko
Expert 3665 points
Part Number: TAS2563
Other Parts Discussed in Thread: , PPC3-EVM-MB, PP-SALB2-EVM

Tool/software:

Hi team,

Could you help below to TAS2563 and customer would consider to run for their new project?

Thanks!

1. For in-system tuning, is HW connected structure as below, right? 

PC(install PPC3 SW) -->  PPC3-EVM-MB --> TAS2563YBGEVM-DC --> connect to customer's PCB board

2. For in-system tuning, which pins customer should connect to TAS2563YBGEVM-DC?

3. To protect amplifier and  run in-system tuning, need below EVMs, right?

EVMs

Application

PP-SALB2-EVM + TAS2563YBGEVM-DC

Learning amplifier to build parameters to protect amplifier

PPC3-EVM-MB + TAS2563YBGEVM-DC

1. Adjust parameters even no connect to customer's PCB board

2. Run in-system tuning when connect to customer's PCB board

4. When adjust done, will get a cfg file, right? And how can customer implement in their project SW? 

5. Also anything I miss above?

Thanks!

    Hello,

    Is the customers application an android based system? This will alter the response to your questions. Slight smile

    Hi Sydeny,

    Please see the reply from customer in below.

    No, it is not an android-based system.

    We do not have any OS in our system. Thanks.

    Yes, for in system tuning without an android based system both the PPC3-EVM-MB and TAS2563YBGEVM-DC will be needed and connected to the PPC3 software. To do the in system tuning, bring out the I2C pins from the device on the end equipment and connect them to the TAS2563YBGEVM-DC. The only thing you will need to do is disconnect the device that is on the EVM so only the device on the end equipment is recognized and controlled.

    The customer should bring out the SDA and SCL pins on their system and connect them to the EVM.

    Correct. Speaker characterization should be done with the EVM though, not with the in system device. For speaker characterization the following document can be referenced: https://www.ti.com/lit/ab/slaa952/slaa952.pdf?ts=1733935700070&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTAS2563. 

    After the speaker has been characterized, they can then move to in system tuning.

    Yes when tuning is finished they can save configuration and header / binary files to use in their SW.

    Hi Sydney,

    Please see some reply from customer, could you help check? Thanks!

    I would like to know more details about bring out wires.  Since the components on the wristwatch are usually not too large (the PCB is also usually small), I would like to reserve test pins (as large as they can) during the design phase.

    More precisely,

     I need to bring out SBCLK 1, SBCLK 2, SDIN 1, SDIN 2, FSYNC, VDD (1.8V) and GND (ground) pins on the TI EVM board and my PCB, right?  (My PCB will have a TAS 2563 on it.)

    In addition, I also need to pull out the SCL/SDA (or any I2C/I2S signal wires related to audio) of my audio codec and connect them to the aforementioned pins, correct?

    Thank you!

    Hi Zoe, 

    For in system tuning the customer just needs to bring out the I2C pins on their board to connect to the EVM. If they bring out the clocks, power, and audio from the EVM it defeats the purpose of in system tuning because they are no longer testing with their end system. The purpose of in system tuning is to adjust the tuning / registers of the in system device while the device is in its end system state (audio input, power, clocks, etc.). This way the customer can tune the device exactly how it will be in production. 

    With the method of bringing out all the clocks, power, and audio from the EVM it is not much different than testing with the EVM + their end system speaker. If this is what they are wanting to do I recommend bringing out the wires from their end system speaker and connecting to the EVM as this would be much simpler.

    Hi Sydney,

    Please see some reply from customer, could you help check? Thanks!

    Our system do not have the operating system (OS). How could we implement the configuration and header / binary files to use in our SW?
