SEMICONDUCTOR TECHNICAL DATA

The MC100EP223 is a low skew 1–to–22 differential driver, designed

with clock distribution in mind. It accepts two clock sources into an input

multiplexer. The selected signal is fanned out to 22 identical differential

outputs.

The EP223 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 840F–02

The EP223 HSTL outputs are not realized in the conventional

manner. To minimize part–to–part and output–to–output skew, the HSTL

compatible output levels are generated with an open emitter

architecture. The outputs are pulled down with 50Ω to ground, rather

than the typical 50Ω to V

pullup of a “standard” HSTL output.

DDQ

Because the HSTL outputs are pulled to ground, the EP223 does not

utilize the V supply of the HSTL standard. The output levels are

DDQ

derived from V

In the case of an asynchronous control, there is a chance of

generating a ‘runt’ clock pulse when the device is enabled/disabled. To

avoid this, the output enable (OE) is synchronous so that the outputs

will only be enabled/disabled when they are already in the LOW state.

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 22 differential pairs will be used and therefore terminated. In

the case where fewer than 22 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.
