The SY10/100E111A/L are low skew 1-to-9 differential
driver designed for clock distribution in mind. The SY10/
100E111A/L's function and performance are similar to the
popular SY10/100E111, with the improvement of lower
jitter and 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.
The E111A/L are 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
pd
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 that 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) of the output(s)
being used which, while not being catastrophic to most
designs, will mean a loss of skew margin.
The E111A/L, as with most other ECL devices, can be
operated from a positive V
CC
supply in PECL mode. This
allows the E111A/L to be used for high performance clock
distribution in +5V/+3.3V systems. Designers can take
advantage of the E111A/L'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
terminating voltage.
