CDCE421RGET TI Clock Generator | 24-VQFN（4X4） | 0.35ps RMS Jitter, 0.9V to 1.1V Core

Product Overview

The CDCE421RGET from Texas Instruments is a high-performance clock generator and jitter cleaner designed for demanding applications requiring ultra-low phase noise and jitter. It integrates a fractional-N PLL with a voltage-controlled oscillator (VCO) to generate output frequencies from 0.5 MHz to 1.175 GHz. The device operates from a 0.9V to 1.1V core supply and supports multiple output formats including LVDS, LVPECL, and LVCMOS. Housed in a compact 24-VQFN (4x4 mm) package, it is ideal for space-constrained designs.
