LMK04228NKDT TI Clock Jitter Cleaner | 64-WQFN (9x9) | Ultra-Low Jitter, Dual PLL

Product Overview

The LMK04228NKDT 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 PLLs, a voltage-controlled oscillator (VCO), and programmable loop filters to provide flexible clock generation and cleaning. The device operates over a wide frequency range and supports multiple output formats including LVDS, LVPECL, and LVCMOS. Housed in a compact 64-pin WQFN (9x9 mm) package, it is ideal for space-constrained designs.
