Overview
The MC100EP90DT is a triple ECL to LVPECL/PECL translator produced by onsemi. This device is designed to receive differential LVECL or ECL signals and translate them into differential LVPECL or PECL output signals. It is part of the 100 Series, which includes temperature compensation, making it suitable for a wide range of high-speed applications. The device operates with multiple power supply configurations and features a VBB output for interfacing with single-ended LVECL or ECL signals.
