must be supplied by the I/Q baseband source with ±6µA capability.
Note 4: Guaranteed by design and characterization.
Note 5: When enabled, turbolock is active during acquisition and injects boost current in addition to the normal charge-pump current.
Note 6: Charge Pump Compliance range is 0.5V to V
