Frequency calculation formula | f’ =f/2^n | T’ =T*2^n | (n is the number of JK triggers used for frequency division ) Enter the binocular output end to the next JK trigger action to output frequency output four -point clock signal, and so on.Ĥ. Four input terminals (J, K, ~ 1pre, ~ 1CLR) input to high levelĢThe image that is easy to analyze needs to adjust the input clock frequency parameters, accept frequency parameters, and the number of display gridsģ. In the same way, combining four or more JK triggers can achieve more frequency frequency Summarize:ġ. Then connect the output to the next JK trigger clock end CLKĪs shown in the figure, a simple quarter frequency is implemented Display the output access logic analyzer as follows Let's talk about the principle of JK trigger: 74HC112N_4V JK trigger chip has seven pins in input, K input, ClockClock pulse input, Presetenter, Clearenter, Q \mathsf C l e a r Enter the same high level VCC CLKPick up the number clockĬlear can add ground end to stop frequent divisionĪs shown in the figure, a simple dual -frequency frequency Display the output access logic analyzer as follows ![]() DIgital power(VCC) Digital power supply.JK trigger implementation clock signal frequency division
