Overview
The MC100EP14DT 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 when using the VBB output. The MC100EP14DT ensures minimal skew within and between devices, making it ideal for high-frequency clock distribution systems. The device features a synchronous enable function to avoid runt clock pulses and includes an internally generated voltage supply (VBB) for rebiasing AC coupled inputs and serving as a switching reference voltage for single-ended inputs.
