Overview
The MC100LVEP14 is a high-performance, 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/HSTL input signals, which can be either differential or single-ended. The MC100LVEP14 is optimized for minimal skew within and between devices, ensuring precise clock distribution across the backplane or board. It operates in PECL mode with a positive VCC supply and in NECL mode with a negative VEE supply, making it versatile for various system configurations.
