The phase-locked loop CD4046 in common usage of integrated circuit is a universal CMOS PLL integrated circuit.Its feature is that its supply voltage ranges widely(3V－18V)and the input impedance is high(about 100MΩ),dynamic power consumption is low.When the core frequency f0 is 10KHZ,the power consumption is just 600μW and it is a micro-power module.The following picture is the pins arrangement of CD4046 and it adopts 16 feet dual inline type. The functions of pins is as follows.
