Webb28 mars 2024 · PLLs are used primarily to generate one or more faster or slower clocks from a reference clock. You might have say a fixed 100MHz crystal, but then want to run your CPU at 2GHz, so a PLL is required to increase the frequency (a 2GHz clock crystal … Webb31 juli 2024 · The PLL lets you be flexible with clock speed even after you've built the board, and of course, it lets you generate many different frequencies from the one onboard oscillator. Honestly, just having a PLL so you can generate many frequencies …
