SEMICONDUCTOR TECHNICAL DATA

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

LOW–VOLTAGE

1:20 DIFFERENTIAL

the V

output is used. The selected signal is fanned out to 20 identical

differential outputs.

ECL/PECL CLOCK DRIVER

• 150ps Part–to–Part Skew

• 50ps Output–to–Output Skew

• Differential Design

• V

Output

• Voltage and Temperature Compensated Outputs

• Low Voltage V Range of –2.375 to –3.8V

• 75kΩ Input Pulldown Resistors

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 t distributions

from lot to lot. The net result is a dependable, guaranteed low skew

device.

CASE 848D–03

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 V

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.
