LMKDB1104FS85REXR TI Clock Buffer | 28-VQFN（4X4） | 1.8V, 85fs RMS Jitter

Product Overview

The LMKDB1104FS85REXR is a high-performance clock buffer from Texas Instruments, designed to distribute low-jitter clock signals in demanding applications. It features four differential outputs with 85fs RMS phase jitter (12 kHz to 20 MHz) and operates from a 1.8V supply. Housed in a compact 28-VQFN (4x4 mm) package, it supports frequencies up to 2.5 GHz and includes an integrated LDO for enhanced PSRR.

Detailed Technical Specifications

Key Features
