1.

In order to achieve best phase noise performance 1V peak level is suggested.

2.

The frequency step is related to the PFD input frequency as follows:

3.

see relationship between ICP and REXT in the Circuit Description section (Charge Pump)

4.

The level of the spurs may change depending on PFD frequency, Charge Pump current, selected channel and PLL loop

BW.

5.

Guaranteed by design and characterization.
