As for the CPout pin, this is the charge pump output which can range from 0 to 2.5V, as it is powered by a 2.5V regulator. If this voltage falls below 0.5 V or goes above 2.0 V, then the Vtune lock detect will consider this unlocked. When the VCO is calibrated, this targes a voltage of around 1.2 volts, but this voltage can "tune" to adjust the VCO frequency. j# i' I4 F; ~2 j5 Y& W6 R- e: y l- L9 x: ^& Q$ D# ^.
