Abstract :
This paper presents a novel architecture of on-chip clock generation employing a network of oscillators synchronized by the distributed all-digital PLLs (ADPLLs). The implemented prototype has 16 clocking domains operating synchronously in a frequency range of 1.1-2.4 GHz. The synchronization error between the neighboring clock domains is less than 60 ps. The fully digital architecture of the generation offers flexibility and efficient synchronization control suitable for use in synchronous SoCs.
