Low-Voltage 1:20 Differential
ECL/PECL Clock Driver
MC100EP221
The MC100EP221 is a low skew 1–to–20 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 single–ended if
the VBB output is used. The selected signal is fanned out to 20 identical
differential outputs.
• 150ps Part–to–Part Skew
• 50ps Output–to–Output Skew
• Differential Design
• VBB Output
• Voltage and Temperature Compensated Outputs
• Low Voltage VEE Range of –2.375 to –3.8V
• 75kΩ Input Pulldown Resistors

1:20 DIFFERENTIAL
ECL/PECL CLOCK DRIVER
The EP221 is specifically designed, modeled and produced with low
skew as the key goal. Optimal design and layout serve to minimize gate–
to–gate 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 50Ω, 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 10–20ps) of the output(s) being used
which, while not being catastrophic to most designs, will mean a loss of
skew margin.

The MC100EP221, as with most other ECL devices, can be operated from a positive VCC supply in PECL mode. This allows
the EP221 to be used for high performance clock distribution in +3.3V or +2.5V systems. Designers can take advantage of the
EP221’s performance to distribute low skew clocks across the backplane. 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.
