Low Voltage 1:10 Differential HSTL
Clock Fanout Buffer
The MC100ES8111 is a bipolar monolithic differential clock fanout buffer.
Designed for most demanding clock distribution systems, the MC100ES8111
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 high performance
clock distribution in computing, networking and telecommunication systems.

Functional Description
The MC100ES8111 is designed for low skew clock distribution systems and
supports clock frequencies up to 625 MHz. The device accepts two clock
sources. The CLK0 input accepts HSTL compatible signals and CLK1 accepts
PECL compatible signals. The selected input signal is distributed to 10 identical,
differential HSTL compatible outputs.
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 10 outputs are used, the output pairs on the same package
side as the parts being used on that side should be terminated.
The HSTL compatible output levels are generated with an open emitter
architecture. This minimizes part-to-part and output-to-output skew. The
open-emitter outputs require a 50
DC termination to GND (0 V). The output
supply voltage can be either 1.5 V or 1.8 V, the core voltage supply is 3.3 V. The
output enable control is synchronized internally preventing output runt pulse
generation. Outputs are only disabled or enabled when the outputs are already
in logic low state (true outputs logic low, inverted outputs logic high). The internal
synchronizer eliminates the setup and hold time requirements for the external
clock enable signal. The device is packaged in a 7x7 mm2 32-lead LQFP
package.
