SEMICONDUCTOR TECHNICAL DATA
The MC10E/100E111 is a low skew 1-to-9 differential driver, designed
with clock distribution in mind. It accepts one signal input, which can be
either differential or else single-ended if the VBB output is used. The
signal is fanned out to 9 identical differential outputs. An enable input is
also provided. A HIGH disables the device by forcing all Q outputs LOW

skew as the key goal. Optimal design and layout serve to minimize gate to
gate skew within-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.
both sides of the differential output are terminated into 50Ω, even if only
one side is being used. In most applications, all nine differential pairs will
be used and therefore terminated. In the case where fewer than nine
pairs are used, it is necessary to terminate at least the output pairs on the
same package side (i.e. sharing the same V
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.

1. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the
differential output signals. See
ECL Data Book (DL140/D).
2. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal. See
Definitions and T esting of ECLinPS AC Parameters
3. Enable is defined as the propagation delay from the 50% point of a negative transition on EN
(or a negative transition on Q
of a negative transition on Q (or a positive transition on Q

8. VPP(min) is defined as the minimum input differential voltage which will cause no increase in the propagation delay . The VPP(min) is AC limited
for the E111 as a differential input as low as 50 mV will still produce full ECL levels at the output.
