Hi uveuvenouve,

SGTL5000 need an external oscillator connected to SYS_MCLK pin to work, and this should be between 8.0and 27MHz.

I have an SGTL5000 datasheet and SGTL5000 Initialization and Programming document, but these are confidential and can be provided under NDA only. (Non Disclosure Agreement). If you already have a valid NDA with NXP, please create a new case here. Please use your company email address and provide following information.

End Customer: ?

End Application: ?

Country: ?

Annual Volume: ?

If you haven't a valid NDA yet, and you would like to sign a new one, please create a new ticket here and our NXP representative for NDA matters will take you through the process.
