Without phase-locked loops, we’d all still be living in caves, just getting by with stone knives and bearskins.
I’m not usually one to go in for sensationalized topics. Clickbait irritates me. But believe me when I say I’m not overstating the importance of phase-locked loops. They live at the heart of every computer system. Phase-locked loops are what make spread-spectrum RF like WiFi and Bluetooth possible.
Really into IoT? You’ve got phase-locked loops to thank. And you know what? Phase-locked loops are tired of being ignored by people who don’t know what they’re all about and how important they are! So if I were you, I’d do the socially responsible thing and watch this video.
Then probably tweet something out about PLLs, saying you’re sorry and telling them how much you love them. And if you do it right, maybe, just maybe, your junk won’t crash today.
