Charge-Pump Current Direction

The direction of the charge-pump (CP) current pulse can be changed by the SPI register settings. It determines

in which direction CP current will regulate (Reference Clock leads to Feedback Clock). Most applications use the

positive CP output current (power-up condition) because of the use of a passive loop filter. The negative CP

current is useful when using an active loop filter concept with inverting operational amplifier. The Figure below

shows the internal PFD signal and the corresponding CP current.
