Overview
The MC100LVEP111 is a low skew 2:1:10 differential driver designed specifically for clock distribution applications. It accepts two clock sources into an input multiplexer, making it versatile for various timing needs. The device supports PECL (Positive ECL), HSTL (High-Speed Transistor Logic), and NECL (Negative ECL) input signals, which can be either differential or single-ended when using the VBB output. This component is optimized for minimal skew, ensuring precise clock distribution across the backplane or the board.
