LOW VOLTAGE, 1:15 DIFFERENTIAL
ECL/PECL CLOCK DIVIDER AND FANOUT BUFFER
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.
Features
Functional Description
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 ÷2 outputs. For the functionality of the MR control input, see
Figure 5. Functional
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.
