Help to translate jitter design constraint in a frequency synthesizer design with 4046 and 4017 ICs
I'm trying to design a frequency synthesizer with the old-school 4046 and 4017 ICs, with a scaling factor N = 1,5,7,10.
The input signal is a square wave with adjustable frequency from 1 kHz to 10 kHz.
I want to get a time jitter < 1% of the…

Calculating Rs Value for 32kHz Pierce-Gate Crystal Oscillator Circuit
Edit: My primary objective is to learn the mathematical model to compute the load resistor \$R_s\$ to satisfy a given crystal's drive level, not just fixing the one instance below.
I'm building a Pierce-Gate oscillator circuit using a 74HC4060 and…

Strange parameters in datasheet of 74HC4046
In datahseet of 74HC4046, page. 10.
Why the typical value may bigger than the max. value, or lower than the min. value? I don't think it's a typo, because there are others like this, such as p. 16
Any reason? What "typical" mean?
