Charge Pump Current Specification Definitions
I1 = Charge Pump Sink Current at V
I2 = Charge Pump Sink Current at V
I3 = Charge Pump Sink Current at V
I4 = Charge Pump Source Current at V
I5 = Charge Pump Source Current at V
I6 = Charge Pump Source Current at V
∆V = Voltage offset from the positive and negative rails. Dependent on the VCO tuning range relative to Vcc and GND. Typical values are between 0.5V and
1.0V.
