Other Parts Discussed in Thread: CD74HC4017, , CD4046B, CD74HC4046A
I am attempting to use a SN74LV4046A PLL coupled with 4x CD74HC4017 counters to take a 0-4Hz input signal and boost that to a 0-10kHz range output. I have had very limited success at this point. I can manage to get 100x multiplication factor by setting C1 = 10nF, R1 = 50k, R2 = no resistor but this only works in a small band near 20Hz...I need this to operate down to about 0.2Hz input with an output of 200Hz out. I have no previous experiance working with PLLs so I do not know how to properly set them up. Also, the datasheets on this are difficult to follow when you've never done this before.
Am I trying to get too much bandwidth here? Do I need to use two seperate PLLs with 100x multiplication factor each to accomplish the 1000-10000x factor I need? Can someone tell me what Resistor and Capacitor values to use and give a quick explanation of the math involved to determine those values?
