PLL Type 2 Design with Extra Pole
This tool calculates PLL loop components. This algorithm is simple, in that it leaves the charge pump current sizing to the user. In practice the loop filter resistor is sized for the phase noise requirement, which in turns leads to a charge pump current requirement. The bandwidth is sized to suppress fractional-N noise or reference spur noise, which is dependent on phase noise requirements. The sizing also does not account for variation in Kv.
