描述 Description

The ZL30168 is a Quad Channel Enhanced?Clock Translator.? Four independent channels can function as DPLLs,?NCO's or?OTN clock generators based on buffer-fill levels.??It can accept?any frequency from 1kHz to 750MHz and generate any frequency from 1Hz to 750MHz to support any communication service over optical networks.?The ZL30168 operates from a single crystal resonator or clock oscillator supporting eight input references configurable as single ended or differential. It supports eight high performance LVPECL outputs and eight high performance LVCMOS outputs.
