LMK5C33414ARGCTS1

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMK5C33414ARGCTS1 is a network synchronizer and jitter cleaner featuring three Digital Phase-Locked Loops (DPLLs) paired with three Analog Phase-Locked Loops (APLLs). It provides four differential or single-ended reference inputs supporting frequencies from 1Hz to 800MHz. The device generates up to 14 differential outputs, configurable for formats including HSDS, AC-LVPECL, LVDS, and HSCL, with output frequencies ranging from 1Hz to 1250MHz. A proprietary Bulk Acoustic Wave (BAW) VCO in APLL3 delivers ultra-low jitter performance. The component operates within a -40°C to 85°C temperature range and is housed in a 64-pin VQFN package.
