1:9 Differential Clock Driver
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
and all Q outputs HIGH.

The device 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-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 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 VCCO) 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.

2. VCMR is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level
must be such that the peak to peak
voltage is less than 1.0 V and greater than or equal to VPP(min).

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
Definitions and Testing of ECLinPS AC Parameters in Chapter 1 (page 112) of the Motorola High Performance
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 Testing of ECLinPS AC Parameters in Chapter 1 (page 112) of the Motorola High Performance ECL Data Book (DL140/D).
3. Enable is defined as the propagation delay from the 50% point of a negative transition on EN to the 50% point of a positive transition on Q
(or a negative transition on Q).
Disable is defined as the propagation delay from the 50% point of a positive transition on EN to the 50% point
of a negative transition on Q (or a positive transition on Q).
4. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.
5. The setup time is the minimum time that EN must be asserted prior to the next transition of IN/IN to prevent an output response greater than
75 mV to that IN/IN transition
(see Figure 1).
6. The hold time is the minimum time that EN must remain asserted after a negative going IN or a positive going IN to prevent an output response
greater than
75 mV to that IN/IN
transition (see Figure 2).
7. The release time is the minimum time that EN must be deasserted prior to the next IN/IN transition to ensure an output response that meets
the specified IN to Q propagation delay and
output transition times (see Figure 3).
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.
