About bandwith of PLL

For the LPF in PLL, is the bandwith of the PLL only related to the R?Is the C1 and C2 connected with the bandwith?
Thanks!

the R and C1 form one zero, and the other capacitor c2 form one pole, and the pole and the zero form the bandwidth of LPF of PLL.

if u check the TF of the PLL u will find that the BW is related to the lop filter components
