Overview
The MC100EP14DTG is a low skew 1-to-5 differential driver designed by Onsemi, specifically tailored 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 conditions and can also rebias AC coupled inputs. The MC100EP14DTG ensures minimal skew within and between devices, making it ideal for high-frequency clock distribution systems.
