Low Voltage 2.5/3.3 V Differential ECL/
PECL/HSTL Fanout Buffer
The MC100ES6111 is a bipolar monolithic differential clock fanout buffer. Designed for most
demanding clock distribution systems, the MC100ES6111 supports various applications that
require distribution of precisely aligned differential clock signals. Using SiGe:C technology and
a fully differential architecture, the device offers very low skew outputs and superior digital
signal characteristics. Target applications for this clock driver is high performance clock
distribution in computing, networking and telecommunication systems.

Functional Description
The MC100ES6111 is designed for low skew clock distribution systems and supports clock frequencies up to 2.7 GHz. The device accepts
two clock sources. The CLKA input can be driven by ECL or PECL compatible signals, the CLKB input accepts HSTL or PECL compatible
signals. The selected input signal is distributed to 10 identical, differential ECL/PECL outputs. If V
BB
is connected to the CLKA input and by-
passed to GND by a 10nF capacitor, the MC100ES6111 can be driven by single-ended ECL/PECL signals utilizing the V
BB
bias voltage output.
In order to meet the tight skew specification of the device, both outputs of a differential output pair should be terminated, even if only one
output is used. In the case where not all ten outputs are used, the output pairs on the same package side as the parts being used on that side
should be terminated.
The MC100ES6111 can be operated from a single 3.3 V or 2.5 V supply. As most other ECL compatible devices, the MC100ES6111 supports
positive (PECL) and negative (ECL) supplies. The MC100ES6111 is pin and function compatible to the MC100EP111.
