Extended Lock Range Zero-Crossing Digital Phase-Locked Loop with Time Delay

open access: yesEURASIP Journal on Wireless Communications and Networking, 2005
The input frequency limit of the conventional zero-crossing digital phase-locked loop (ZCDPLL) is due to the operating time of the digital circuitry inside the feedback loop.

Hold-in, pull-in, and lock-in ranges of PLL circuits: rigorous mathematical definitions and limitations of classical theory [PDF]

open access: yes, 2015
The terms hold-in, pull-in (capture), and lock-in ranges are widely used by engineers for the concepts of frequency deviation ranges within which PLL-based circuits can achieve lock under various additional conditions. Usually only non-strict definitions
