ZL30364GDG2 Descrizione generale

The ZL30364GDG2 is a cutting-edge clock generator and jitter attenuator IC designed for high-speed communication applications. Its advanced features include integrated digital PLLs for on-the-fly frequency changes and fast lock times, as well as programmable output skew and phase adjustment capabilities for precise timing alignment within the system. With its ability to generate multiple output clocks with low jitter and phase noise, this device is perfect for applications that require accurate timing synchronization
