LMKDB1104Z85REXT TI Clock Buffer | 28-VQFN (4x4) | 1:4 Fanout, 85MHz

Product Overview

The LMKDB1104Z85REXT is a high-performance 1:4 fanout clock buffer from Texas Instruments, designed for low-jitter clock distribution in demanding applications. It operates at a maximum frequency of 85 MHz and is housed in a compact 28-VQFN (4x4 mm) package. The device features LVCMOS/LVTTL compatible inputs and outputs, making it ideal for interfacing with a wide range of logic families. With its low additive jitter (typically 0.1 ps RMS) and wide supply voltage range (2.375V to 3.6V), the LMKDB1104Z85REXT ensures reliable clock distribution in systems requiring high timing accuracy.
