Low Voltage 1:15 Differential

ECL/PECL Clock Divider and

Fanout Buffer

The Motorola MC100ES6222 is a bipolar monolithic differential clock

fanout buffer. Designed for most demanding clock distribution systems,

the MC100ES6222 supports various applications that require the

distribution of precisely aligned differential clock signals. Using SiGe

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 MC100ES6222 is designed for low skew clock distribution systems and supports clock frequencies up to 3 GHz. The

CLK0 and CLK1 inputs can be driven by ECL or PECL compatible signals. Each of the four output banks of two, three, four and

six differential clock output pairs can be independently configured to distribute the input frequency or

÷2 of the input frequency.

The FSELA, FSELB, FSELC, FSELD and CLK_SEL are asychronous control inputs. Any changes of the control inputs require a

MR pulse for resynchronization of the the

÷2 outputs. For the functionality of the MR control input, see Figure 5. , “Functional

Diagram,” on page 7.

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 MC100ES6222 can be operated from a single 3.3V or 2.5V supply. As most other ECL compatible devices, the

MC100ES6222 supports positive (PECL) and negative (ECL) supplies. The MC100ES6222 is pin and function compatible to the

MC100EP222.
