2.5/3.3V Differential LVPECL

1:9 ClockDistribution Buffer

and ClockDivider

The Motorola MC100ES6226 is a bipolar monolithic differential clock

distribution buffer and clock divider. Designed for most demanding clock

distribution systems, the MC100ES6226 supports various applications

that require a large number of outputs to drive precisely aligned clock

signals. Using SiGe technology and a fully differential architecture, the

device offers superior digitial signal characteristics and very low clock

skew error. Target applications for this clock driver are high performance

c loc k dis tribution sy s tems for computing, network ing and

telecommunication systems.

Features:

and metastability

Functional Description

MC100ES6226 is designed for very skew critical differential clock distribution systems and supports clock frequencies from

DC up to 3.0 GHz. Typical applications for the MC100ES6226 are primary clock distribution systems on backplanes of

high-performance computer, networking and telecommunication systems, as well as on-board clocking of OC-3, OC-12 and

OC-48 speed communication systems.

The MC100ES6226 can be operated from a 3.3V or 2.5V positive supply without the requirement of a negative supply line.

Each of the output banks of three differential clock output pairs may be independently configured to distribute the input frequency

or half of the input frequency. The FSEL0 and FSEL1 clock frequency selects are asychronous control inputs. Any changes of the

control inputs require a MR pulse for resynchronization of the

÷2 outputs.
