描述 Description

The ZL30174 features four independent flexible rate conversion clock channels via four digital PLLs and four clock generators. Each channel accepts and generates any frequency from 1 Hz to 900 MHz to support any communication service over optical networks. The ZL30174 operates from a single crystal resonator or clock oscillator supporting up to ten input references configurable as single ended or differential. It generates up to 12 high performance outputs.Click here for secure documentation
