The frequency capture range (2fc) is defined as the

frequency range of input signals on which the PLL will lock

if it was initially out-of-lock. The frequency lock range

(2fL) is defined as the frequency range of input signals on

which the loop will stay locked if it was initially in lock. The

capture range is smaller or equal to the lock range.
