Low-Voltage 1:10 Differential

ECL/PECL Clock Driver

The MC100EP111 is a low skew 1to10 differential driver, designed

with clock distribution in mind. It accepts two clock sources into an input
multiplexer. The input signals can be either differential or singleended if
the VBB output is used. The selected signal is fanned out to 10 identical
differential outputs.

The EP111 is specifically designed, modeled and produced with low

skew as the key goal. Optimal design and layout serve to minimize gate
togate skew within a device, and empirical modeling is used to
determine process control limits that ensure consistent tpd distributions
from lot to lot. The net result is a dependable, guaranteed low skew
device.

To ensure that the tight skew specification is met it is necessary that

both sides of the differential output are terminated into 50

, even if only

one side is being used. In most applications, all ten differential pairs will
be used and therefore terminated. In the case where fewer than ten pairs
are used, it is necessary to terminate at least the output pairs on the same
package side as the pair(s) being used on that side, in order to maintain
minimum skew. Failure to do this will result in small degradations of
propagation delay (on the order of 1020ps) of the output(s) being used
which, while not being catastrophic to most designs, will mean a loss of
skew margin.

The MC100EP111, as with most other ECL devices, can be operated from a positive VCC supply in PECL mode. This allows

the EP111 to be used for high performance clock distribution in +3.3V or +2.5V systems. Designers can take advantage of the
EP111's performance to distribute low skew clocks across the backplane or the board. In a PECL environment, series or
Thevenin line terminations are typically used as they require no additional power supplies. For more information on using PECL,
designers should refer to Motorola Application Note AN1406/D.
