Digital Phase Lock Loops
Digital phase lock loops are critical components of many communication, signal processing and control systems. This exciting new book covers various types of digital phase lock loops. It presents a comprehensive coverage of a new class of digital phase lock loops called the time delay tanlock loop TDTL. It also details a number of architectures that improve the performance of the TDTL through adaptive techniques that overcome the conflicting requirements of the locking rage and speed of acquisition. These requirements are of paramount importance in many applications including wireless communications, consumer electronics and others.
A wide range of Analog PLLs is available off-the-shelf. They are also popular for radio front-end applications. Digital phase-locked loops are typically smaller than analog PLLs, due to their digital phase detector and loop filter. Thus both PLL types:. The result of the lengthy development process is that both Analog PLLs and digital pha se-locked loops are both primarily purchased from off-the-shelf product families. Given their availability limits, chip design teams often must:. They are also fully synthesizable, so they can be customized and implemented in processes across all foundries, as well as non-standard process nodes in a fraction of the time of analog PLLs.

A phase-locked loop or phase lock loop PLL is a control system that generates an output signal whose phase is related to the phase of an input signal. There are several different types; the simplest is an electronic circuit consisting of a variable frequency oscillator and a phase detector in a feedback loop. The oscillator generates a periodic signal, and the phase detector compares the phase of that signal with the phase of the input periodic signal, adjusting the oscillator to keep the phases matched. Keeping the input and output phase in lock step also implies keeping the input and output frequencies the same. Consequently, in addition to synchronizing signals, a phase-locked loop can track an input frequency, or it can generate a frequency that is a multiple of the input frequency. These properties are used for computer clock synchronization, demodulation , and frequency synthesis. Phase-locked loops are widely employed in radio , telecommunications , computers and other electronic applications.

Self-organized synchronization occurs in a variety of natural and technical systems but has so far only attracted limited attention as an engineering principle. In distributed electronic systems, such as antenna arrays and multi-core processors, a common time reference is key to coordinate signal transmission and processing. Here we show how the self-organized synchronization of mutually coupled digital phase-locked loops DPLLs can provide robust clocking in large-scale systems.
