LMK5C33414ARGCR

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMK5C33414A is a network synchronizer and jitter cleaner featuring three Digital Phase-Locked Loops (DPLLs) paired with Analog Phase-Locked Loops (APLLs). It includes four differential or single-ended DPLL inputs supporting frequencies from 1Hz to 800MHz. The device provides fourteen differential outputs capable of generating frequencies up to 1250MHz, with programmable formats including HSDS, AC-LVPECL, LVDS, and HSCL. APLL3 utilizes Bulk Acoustic Wave (BAW) technology for ultra-low jitter generation. The component operates within a temperature range of -40°C to 85°C and is housed in a 64-pin VQFN package.
