Overview
The MC100EP14DTR2G, produced by onsemi, is a 3.3V / 5V 1:5 differential ECL/PECL/HSTL clock driver designed for clock distribution applications. This device accepts two clock sources into an input multiplexer and is optimized for low skew, ensuring precise timing in high-speed systems. It supports both differential and single-ended ECL/PECL input signals, and HSTL inputs can be used under PECL conditions. The device features a synchronous enable function to avoid runt clock pulses and includes an internally generated reference voltage (VBB) for rebiasing AC coupled inputs or single-ended input conditions.
