LMK04828: LMK04828 digital delay feature

Part Number: LMK04828

Hello,

There is a confusing comment in the datasheet:

Is the digital delay resolution and total delay set according to the VCO frequency or clock distribution frequency?

For example,

If the VCO frequency  is 2560MHz and the clock distribution path is 320MHz (VCO frequency divided by 8)
What will be my delay resolution and total delay?

Thanks in advance,

Guy.
