MC100ES6111
The Motorola 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 compatible signals. The selected input signal is distributed to 10 identical, differential ECL/PECL outputs. If VBB is
connected to the CLKA input and bypassed to GND by a 10 nF capacitor, the MC100ES6111 can be driven by single-ended
ECL/PECL signals utilizing the VBB 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 3.3V or 2.5V 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.
