A 4-Step Practical Guide to Optimizing Oscillator Dynamic Phase Noise

The useful thing about quartz is that if you apply a voltage, it will start to vibrate

How RTC enables everything to run accurately

The "punctuality" and "precision" that we are accustomed to all rely on the "timing reference source" of electronic devices - Real-Time Clock (RTC)

How to layout the crystal oscillator on the PCB

The equivalent circuit of a crystal shows a series RLC circuit, representing the mechanical vibration of the crystal, in parallel with a capacitor representing the electrical connection to the crystal, and the crystal oscillator operates towards series resonance.

Detailed explanation of CMOS active crystal oscillator voltage

The average voltage of the square wave is the middle value between the high level and the low level, but this method cannot reflect the true peak-to-peak value.

Analysis of the reasons why the oscillation circuit does not oscillate

If a short circuit is suspected, it is recommended to use the resistance range of a multimeter for measurement. Measure the resistance across the crystal oscillator after powering off:

What is a crystal oscillator?

Crystal oscillators generally refer to quartz crystal oscillators and quartz crystal resonators, which can also be directly called crystal oscillators. Both are made using the piezoelectric effect of quartz crystals.
