Fundamentals of PLLs

We will deliver basic knowledge related to PLL.

In recent years, ICs with PLL functions have become popular, and it seems that the discrete PLL itself is no longer used. PLL ICs are becoming more multi-functional, and control settings are becoming more complex. If you understand what each IC setting means by having basic knowledge of PLL, it will be easier to deal with problems when they occur. Therefore, here we will introduce the basic configuration of an analog PLL.

I will introduce the related basics that I think you need to know about oscillators.

• Oscillator vs Resonator
• Quality Factor
• Jitter
• Phase Noise

Oscillator type

Oscillators also come in many types and functions.

Here, we will introduce various oscillators.
