OK, I'm using a 32KHz crystal in a 74hc4060. Currently I am using one of the dived by 2 outputs to get a 1KHz gate pule as the input to an AND gate along with the input frequency to be measured. So, works fine at 1KHz resolution but I would like to take it on down to 1Hz resolution. So I need a 1Hz gate signal. I want to use the same 32KHz crystal and the '4060 oscillator/13 stage binary counter. I am using 74hc390 decade counters and have a few more on hand. The problem is the QD outputs are not 50% duty cycle. So here is the question:
Could I use a 2KHz output from the '4060 and divide it down through 3 stages of decade counters to get 2Hz, then use the 2Hz to drive a J-K flip flop setup up for toggle mode to get a stable 1Hz with 50% duty cycle?
