TAS2563: Chip related application problems

Tonyx.wu

Part Number: TAS2563

At present, two tas2563rpps are connected to the same I2S. If one pa wants to receive the left channel data of I2S and the other pa wants to receive the right channel data of I2S, how can this pa end be controlled.

Also help to see if this set of driver code is applicable. The product here uses Qualcomm android12 platform

Just to let you know today was a holiday in the US, so we will get back to you on July 5th. However, the best way to configure which channel of audio is selected is to use PPC3 to generate the register configuration, do you have access?

Hi Tony,

As Brian mentioned below, the best way to configure the device is by generating the configuration files from PPC3, you can request access to this software tool within TAS2563 product folder: https://www.ti.com/licreg/docs/swlicexportcontrol.tsp?form_id=272827&prod_no=TAS2563-SW&ref_url=asc_amps_lpaa

I2S input data is handled by register TDM_CFG3 (page=0x00 address=0x09) and TDM_CFG2 (page=0x00 address=0x08):

TDM_CFG3 is used to select which slot is used for each channel, by default this is slot 0 and 1 which would also work for I2S format.
Then TDM_CFG2 can be used to select either L, R or a mix of both by setting bits 5-4 RX_SCFG. There is another option where TDM_CFG3 is ignored and the device selects the slot based on its I2C address, this is mono only (cannot mix two channels together)

And regarding the driver, you may refer to our latest reference codes in our repo: https://git.ti.com/cgit/?q=tas2563

This is the startup log and the log of playing music. Can you help me see what the problem is? At present, I2C and I2S are OK, mainly the operation of PA side registers and the loading of firmware.
