ADV7404 crystal frequency 27.0 or 28.6...MHz?

When comparing data-sheet and Manual_RevB of ADV7403, I found that the 27MHz crystal mentioned in the manual is not touched in the data-sheet.

This confuses me a little. I'm not quite sure if 28.6..MHz (= 4 x NTSC subcarrier) is the right choice for "non-NTSC" applications, or on the other side, if 27MHz will be appropriate for NTSC.

 

Will 28.6...MHz crystal work for all standards?

 

Thanks for your responses,
