It accepts LVCMOS, LVDS, or LVPECL reference inputs and delivers 2VPECL or LVPECL outputs, making it a fit for clocking high-speed ADCs, DACs, FPGAs, and SerDes transceivers in telecom and data-converter applications. The supply range is 3.15 V to 3.45 V, a tight window that demands a clean, regulated rail — a 3.3 V LDO with low noise is the typical pairing. The 2:5 input-to-output ratio means two reference inputs can be muxed to five clock outputs — useful for fan-out in multi-rail clock trees.","metaTitle":"LMK04111SQX/NOPB PLLatinum Clock Generator, 1.08 GHz","metaDescription":"TI PLLatinum clock synthesizer with PLL, 1.08 GHz max, LVCMOS/LVDS/LVPECL input, 2VPECL/LVPECL output.
