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.
