Digital PLL (Determine Kp Ki and Oscillation problem)

[alex2007]

ki kp loop filter

I am trying to do the digital PLL.
(1) phase detector (multiplier)
(2) digital loop filter (Transfer function derived from analog active lead lag filter)
(3) NCO+Cordic

Quetions:

Q1) how to determine Kp and Ki for the digital loop filter?

Q2) how to solve the oscillation problem at the output of (1) and (2)?
