I want to use a 4046 Pll without the internal vco, however I do want to use the source follower for the demod output.
This means I have to have the vco enabled as the enable input enables the vco and the source follower, how do I stop the vco from running or make it stable so its doesnt interfere with the rest of the circuit?, can I just ground the cap inputs, or the r1/r2 inputs?
I guess I could use an extrnal op amp and disable the vco/source follower but if I can save a chip I will.
