ZL30165

In Production

The ZL30165 is the first monolithic Clock Translator in the industry with four independent flexible rate conversion clock channels. Each channel accepts and generates any frequency from 1kHz to 750MHz to support any communication service over optical networks. With very low power consumption, the ZL30165 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....
