	Radio-Electronics.Com :: PLL Phase Detectors
		The phase detector is the core element of a phase locked loop, PLL.
		However the most important difference is whether the phase detector is sensitive to just phase or whether it is sensitive to frequency and to phase.
		Phase detectors that are only sensitive to phase are the most straightforward form of detector.

	Theory And Application Of Sampling Phase Detector
		It combines the far-out phase noise of fundamental oscillators, especially in the microwave frequency range (100 kHz away from carrier frequency and beyond), the excellent long-term stability, and the close-in phase noise of a crystal oscillator (from carrier frequency to 100 kHz away).
		Digital phase lock: This is usually achieved by using a frequency divider to divide the higher frequency of the VCO to the same frequency of the crystal reference.
		Analog phase lock: This is achieved by using an SRD as a comb generator to create a comb of reference frequencies to the frequency of the VCO.

	Phase-Lock Loop Applications Using the MAX9382 - Maxim/Dallas
		Phase differences at the phase detector input produce dissimilar pulse widths on the phase detector "up" and "down" outputs, causing the loop filter voltage to pump up or down as directed.
		A typical phase detector output condition at lock is a series of very short pulses on the "up" and "down" outputs.
		The first response is that produced by a phase detector with a minimum output short pulse width of zero ps.
