MC100EP221

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview Low-Voltage 1:20 Differential ECL/PECL Clock Driver MC100EP221 The MC100EP221 is a low skew 1–to–20 differential driver, designed with clock distribution in mind. It accepts two clock sources into an input multiplexer. The input signals can be either differential or single–ended if the VBB output is used. The selected signal is fanned out to 20 identical differential outputs. 150ps Part–to–Part Skew 50ps Output–to–Output Skew Differential Design VBB Output Voltage and Temperature Compensated Outputs Low Voltage VEE Range of –2.375 to –3.8V 75kΩ Input Pulldown Resistors LOW–VOLTAGE 1:20 DIFFERENTIAL ECL/PECL CLOCK DRIVER The EP221 is specifically designed, modeled and produced with low skew as the key goal. Optimal design and layout serve to minimize gate– to–gate skew within a device, and empirical modeling is used to determine process control limits that ensure consistent t...
