Ash,
I think you have a problem with the circuit values.
I'm running with my Philips data handbook for the HCT4046A and fig 29 which shows the typical centre frequency as a function of C1. For C1 =820 pF, and R1 = 3 kohm, f0 is about 1 MHz. For R1 = 300 kohm, fo is about 10 KHz. Both these values are given for R2 = open circuit. The HCT4060 looks like it is dividing by 128. I dont like your value of R1 = 100 ohm, I think it should be around 10 K ohm to give f0 equal to say 400 KHz and the divider giving about 3 KHz. When I look at your waveforms and see horizontal values like 20 milli seconds, there is no way 100 ohm looks right.
The HC/HCT range of logic runs at 5 to 12 volt + with respect to ground. The MAX is an output filter and can run with a +/- 5 volt supply.
I gather you are a student and this is an exercise,
Hope this helps.
