25MHz Crystal Support

Other Parts Discussed in Thread: TUSB9260

This is a repost with proper title:

Can I use a 25MHz crystal (NOT a crystal oscillator) if FSEL0=3.3V and FSEL1=0? This combination is shown as an example in the Implementation Guide, but  Table 3 lists the crystal options as "reserved". Thanks,

-Turi

    Hello Turi,

    Your configuration of FREQSEL[1:0] is correct for 25MHz, you can use a Crystal or an external oscillator as the clock source, just follow the requirements of Section 6 on TUSB9260's data manual. (http://www.ti.com/lit/ds/symlink/tusb9260.pdf)

    What "Table 3" are you referring to?

    Regards.
