For this week’s QSPICE schematic capture, we’ve got a "A Simple, Low-Voltage Oscillator,” by our friend Alexander Bordodynov. Please send any schematic capture submissions to me at tim.mccune@qorvo.com (Schematic Capture Post #032)
Are these crystal parameters publicized by mfg? I never saw these in a data sheet.
Instead of Q-factor, you can specify Rser.
That’s what I usually do.
Great, does that cover both dF and Q?
For low-frequency quartz, the capacitance coefficient and the series resistance are indicated. I took the information from the spice model. KC = 347.17 “1.84P/5.3F”
