Overview
The MC100EP90DTG 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 features a VBB output for interfacing with single-ended LVECL or ECL signals at the input, which acts as the switching reference under single-ended input conditions. The device requires three power rails (VCC, VEE, and GND) and includes temperature compensation, making it suitable for high-frequency applications.
