Hi guys,

I know there are already several threads about the 4060, but I am still a bit puzzled. This is the first time that I'm working with the IC and I'm not quite sure if I'm simulating it correctly on Multi-sim.
I'm basically using the chip as an oscillator which will output a pulse to an amplifier which finally goes to a speaker. I've created a circuit which I gathered would work after reading the datasheet. From my understanding pins 1,2,3,4,5,6,7,13,15,14 are outputs. However I haven't observed any pulsating output on multi-sim.
Please see circuit below.
Thanks.

 

Please note: In the uploaded circuit the oscillator channel B isn't grounded. It was when I was simulating the ouptut.

 

Try connecting your probe to pin 9,10 or 11 to see if you have a signal there.

 

Yes. 5V from all 3 of those pins.

 

Oscillators can be temperamental when simulated and sometimes don't start.
Try the Use Initial Conditions (UIC) option.

 

Hi

I have Multisim Blu, but it doesn't have the part.
However, I simulated on LTspice. Seems to work ok.
This is an LTspice sim with the TI CD4060B.

Hello again,

When I first posted this thread I had assumed that my connections/circuit may be wrong. However after spending some time trolling the National Instruments forums I have discovered that there was actually an issue with the clocking ability of the 4060 on multisim 9. Looks like they possibly haven't resolved this problem as yet. A member on the NI forum suggested alternatively simulating using the 4020 which is what I am going to do.

Any advice on the 4020, are there any advantages/disadvantages over the 4060, and should i consider not only using it in the simulation but when I'm actually building my circuit as well?

 

You will need to use a separate clock signal generator if you go with the 4020.

 

Yes, discovered that whilst simulating.
Thanks.

I mainly require 2 clock pulses, 1 at 1Hz and 1 at 520Hz. The lack of an internal pulse in the 4020 would mean I'd have to use something like a 555 to generate an initial clock pulse. I fancied the 4060 as it would be driving a speaker and varying pulses from a single chip would have been quite useful.

 

Hello,

It would be easier to create an 512 Hz and an 1 Hz signal as they are multiples of 2.

I would like to using CD4060 and crystal to generate a precisely 1Hz timebase, but if you like to generate 520Hz then you need another circuit, or a 512 hz from CD4060.

 

Yes. I have already considered changing the specs to 512Hz and 1Hz.
Thanks guys.
