Hi, TI team:

Can I use 27M for TDA4? please see the picture.

what is the difference about 25M? because I noticed some design use 25M, but I don't know which one is better.

    For TDA4VM-Q1, yes 27MHz is a supported boot frequency.  Snip-it below from data manual

    WKUP_OSC0 is the boot clock and is required.  Only specific freq are supported.

    OSC1 is an optional clock and is NOT required.  It can be used to generate alternate frequencies. A common usage is to generate audio sampling clock. A range of freq is supported.
