``Cloning'' of SFQ pulses is easy and can be done by a JTL with two
outputs (see Fig. 
).
One junction cannot drive more than two other junctions and if
``fan-outs'' larger than 2 are needed it is a common practice to build
``trees'' of splitters with the output of one splitter connected to
the input of another. In principle, this approach allows arbitrary
large fan-outs to be achieved but it should be noted that each
splitting stage introduces an additional delay of the SFQ pulse and if
the ``tree'' is big enough, the total delay between the incoming pulse
and the wave of its ``clones'' as well as the relative delays between
the ``clones'' may create a serious timing problem.
