Product Overview
The LMK04803BISQE/NOPB from Texas Instruments is a high-performance clock jitter cleaner and frequency synthesizer designed for demanding applications requiring ultra-low phase noise and jitter. It integrates dual phase-locked loops (PLLs) with voltage-controlled oscillators (VCOs) and provides up to 14 differential clock outputs. The device operates from a 3.3V supply and is housed in a compact 64-pin WQFN (9x9 mm) package. It supports frequencies up to 3.1 GHz and offers programmable output formats including LVDS, LVPECL, and LVCMOS.
