Low Voltage 1:5 Differential LVDS

The MC100ES7014 is a LVDS differential clock fanout buffer. Designed for

the most demanding clock distribution systems, the MC100ES7014 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 are in high performance clock

distribution in computing, networking and telecommunication systems.

The MC100ES7014 is designed for low skew clock distribution systems and

supports clock frequencies up to 1000MHz. The device accepts two clock

sources. The CLK0 input accepts LVDS or HSTL compatible signals and CLK1

accepts PECL compatible signals. The selected input signal is distributed to 5

identical, differential LVDS compatible outputs.

Features

• 1:5 differential clock fanout buffer

• 50 ps maximum device skew

• SiGe Technology

• Supports DC to 1000 MHz operation

• LVDS compatible differential clock outputs

• PECL and HSTL/LVDS compatible differential clock inputs

• 3.3V power supply

• Supports industrial temperature range

• Standard 20 lead TSSOP package
