CDCM1804RTHR TI Clock Buffer | 24-VQFN (4x4) | 1:4 Fanout, 2.5V/3.3V

Product Overview

The CDCM1804RTHR from Texas Instruments is a high-performance, low-skew, 1:4 clock buffer designed for distributing clock signals in demanding applications. It operates from a 2.5V or 3.3V power supply and features four differential outputs (LVPECL) or eight single-ended outputs (LVCMOS) depending on configuration. The device is housed in a compact 24-pin VQFN (4x4 mm) package, making it ideal for space-constrained designs. With ultra-low additive jitter (typically 0.1 ps RMS) and skew (typically 20 ps), it ensures precise clock distribution for high-speed digital systems.

Detailed Technical Specifications

Key Features

• 1:4 fanout with differential or single-ended outputs
