rc oscillator using 74hc04
Hello,
I need to use the 4046 PLL, and i don't know how to choose RC values that are optimum to minimize jitter&noise of the VCO?
In general, should I use a high C value, thus charging/discharging the cap with higher current, or use a lower C ?
Because I need a narrow VCO domain, offset should be used so the VCO range doesn't start from very low frequency?
Thanks
