25M multiply to 2450M

N=49. is that right?

if it's right, then what are bits[15:8]?

how to calculate?

the data sheet confuse me

thank you

Hi

Those bits consist the Feedback Divider N.I found a section in the datasheet that explained this well.

The N divider value in Bits[15:8] is one part of the total PLL multiplication available. The second part is the fixed divide by two element in the feedback path. Therefore, the total PLL multiplication value is 2N. The valid N divider range is 10× to 255×. The default N value for Bits[15:8] = 25. This sets the total default PLL multiplication to 50× or 2N.
