Overview
The MC100LVEP14DTR2G, produced by onsemi, is a low skew 1-to-5 differential driver designed specifically for clock distribution applications. This device accepts two clock sources into an input multiplexer and supports ECL/PECL and HSTL input signals, which can be either differential or single-ended. The use of the VBB output allows for single-ended input operation under certain conditions. The MC100LVEP14 is optimized for high-performance clock distribution in systems operating at 2.5V or 3.3V, making it suitable for a wide range of applications requiring precise clock signal distribution.
