WebSep 17, 2024 · The free-running frequency of the VCO f fr represents what the CDR knows about the frequency (f p) of the signal to lock into. The difference (f p – f fr ) is a … WebAug 4, 2013 · When the PLL is unlocked, the VCO oscillates at the frequency Ffr, called the free-running frequency of VCO. The PLL can achieve the lock again if FREF gets close enough to Ffr. This narrow band ( Fc) of frequency, centered at Ffr so that the initially unlocked PLL acquires the lock again, is called the ‘capture range’ of the PLL ...
