AD8302 LF 2.7 GHz RF/IF Gain and Phase Detector
www.analog.comThe AD8302 includes a phase detector of the multiplier type, but with precise phase balance driven by the fully limited signals appearing at the outputs of the two logarithmic amplifiers. Thus, the phase accuracy measurement is independent of signal level over a wide range. The phase and gain output voltages are simultaneously available

Fractional/Integer-N PLL Basics - Texas Instruments
www.ti.comTo accomplish this, a reference frequency must be provided to the phase detector. Typically, the TCXO frequency (Fx), is divided down (by R) “on-board” the PLL IC. The phase detector utilizes this signal as a reference to tune the VCO and, in a “locked state,” it must be equal to the desired output frequency, Fvco, divided by N.
