how to select pump
all,
I am doing a PLL design, I don't know how to select the charge pump current. As we know, the pump current is the important fact in bandwidth, stability. And we must meet the reasonable trade-off between the value of filter components and the current. So how to do this trade-off, what's the resonable value for charge pump current?
