Other Parts Discussed in Thread: TAS2563,

Hi Sirs,

As title, my customer encounter problem with TAS2X63 EVM + LB2, while we are not able to resolve the problem with 1.8V VDDIO based on the thread at
TAS2563: TAS2563 Hardware Check Error with Characterization Page - Audio forum - Audio - TI E2E support forums

Would you please assist us in reviewing the configuration?

Thank you and Best regards,

Hello Wayne,

From the picture, nothing looks wrong with the hardware setup itself. Is this EVM able to produce sound when using it normally or in ROM mode? If not, make sure the computer is properly setup to output audio and set to 100% volume.

Best Regards,

Justin Beigel

Hello Justin, Thanks a lot. The TAS2563 QFN EVM works in tuning and ROM modes both with no LB2 connected....Wayne Chen

Hello Wayne,

Can you try different combinations of IOVDD and VCC-IO jumper settings on the TAS2x63EVM? I have had some issues with the LB2 in the past with certain voltages.

Best Regards,
