well, it is kind of a huge question, since PLL alone is such a topic you
can write a whole book. Basically, one of the key thing is the desigh of
the low pass filter which is called loop filter. There is no fixed

time and the output phase noise. The idea is the choice of loop
bandwidth, if it is large, it will help you accelerate your acquistion,
