Default Phase frequency Detector

Hi!
I need help understanding a conventional phase/frequency detector.I
consists of 6 two input NAND gates and 3 three input NAND gates.It
compares the phase and generates UP and DOWN signals.I was wondering
why the dead zone is high specially when there is a large reset delay
path.
