Low Voltage 2.5/3.3 V Differential

ECL/PECL/HSTL Fanout Buffer

The MC100ES6210 is a bipolar monolithic differential clock fanout buffer.

Designed for most demanding clock distribution systems, the MC100ES6210

supports various applications that require to distribute precisely aligned

differential clock signals. Using SiGe technology and a fully differential

architecture, the device offers very low clock 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 MC100ES6210 is designed for low skew clock distribution systems and supports clock frequencies up to 3 GHz. The

device consists of two independent 1:5 clock fanout buffers. The input signal of each fanout buffer is distributed to five identical,

differential ECL/PECL outputs. Both CLKA and CLKB inputs can be driven by ECL/PECL compatible signals.

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 MC100ES6210 can be operated from a single 3.3 V or 2.5 V supply. As most other ECL compatible devices, the

MC100ES6210 supports positive (PECL) and negative (ECL) supplies. The is function and pin compatible to the MC100EP210.
