TMS320C6424: Recommended crystal oscillator frequency tolerance & stability for audio applications (PCM4)

Part Number: TMS320C6424

Hi,

I would like to have recommendation on a crystal oscillator that suit for audio applications, specifically PCM4.

Please advise what shall be its accuracy (tolerance & stability in ppm) in order to achieve best performance.

Best Regards,

Haim.

  • Hello Haim, 

    Thank you for the query.

    The crystal requirements are captured in section 

    6.6.1 Clock Input Option 1- Crystal

    of 

    https://www.ti.com/lit/ds/symlink/tms320c6424.pdf

    The crystal selection is based on your specific system requirements. That is why the datasheet says, "The user should select crystals with low enough ppm to ensure good audio quality for the specific application."  The user in this case is the system designer.
