Description
The SK10/1000LVE111E is a low skew 1-to-9 differential driver
designed with clock distribution in mind. The SK10/
100LVE111E’s function and performance are similar to the
SK100E111, with the added feature of low voltage operation.
It accepts one signal input which can be either differential or
single-ended if the V
BB
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 focing 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 a device, and
characterization 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 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)

Preliminary Information
This document contains information on a new product. The parametric

of the output(s) being used which, while not being
catastrophic to most designs, will mean a loss of
skew margin.
The SK10/100LVE111E, as with most other ECL
devices, can be operated from a positive VCC
supply in PECL mode. This allows the LVE111E
to be used for high performance clock distribution
in +3.3V systems. Designers can take advantage
of the LVE111E’s performance to distribute low
skew clocks across the backplane or the board.
In a PECL environment, series or Thevenin line
terminations are typically used as they require no
additional power supplies. For systems
incorporating GTL, parallel termination offers the
lowest power by taking advantage of the 1.2V
supply as a terminating voltage.
