				0.1Hz~500kHz signal source circuit made by LM567
			 
			 
			
		
		
		
			
			Manifold block LM567 is the high stability phase-locked loop circuit which has the phase-locked loop circuit. Using the internal “controllable current oscillator” of this manifold block can make a simple adjustable low-frequency signal source, so the maintenance will be very convenient. The circuit is as shown.
