Notice that i also hold this oll at a different angle than two. The theory and mathematical models used to describe plls are of two types. In a multiple pll design, the first impression may bring a designer to think the plls are independent and therefore the initialization sequence would function independently. Pllphase locked loops electronic circuits and diagrams. This observation is in most cases wrong, leading to redesign and. This is because pll is the last step and in my opinion, the easiest step to learn, and once you have done oll, you can go straight into pll without much hesitation.
