C- MOSIC4046 PLL having the main function of a maximum operating frequency of iMHz integrated circuit, which is connected to the programmable divider, can constitute the input
frequency increases t times the circuit. Phase comparator PC2 check, t phase 1 is equal to the frequency of the output of the frequency divider circuit and t which outputs ) ~ vP-P signal via the loop filter (roar -R2, G soap) after filtering vco oscillation frequency control. vco variable range of jf a field -f, In is from the input frequency fiv to N- ffw. Consider Journal circuit errors and long-term stability, actually increase the number of safety margin.
