Charge Pump Current Specification Definitions
I1 = Charge Pump Sink Current at VCP
I2 = Charge Pump Sink Current at VCP
I3 = Charge Pump Sink Current at VCP
I4 = Charge Pump Source Current at VCP
I5 = Charge Pump Source Current at VCP
I6 = Charge Pump Source Current at VCP
∆V = Voltage offset from the positive and negative rails. Dependent on the VCO tuning range relative to V
1.0V.
