Figure 46. A 32 × 5 Crosspoint Array Using Two AD8106s or Two AD8107s
The inputs are uniquely assigned to each of the 32 inputs of the
two devices and terminated appropriately. The outputs are wire-
OR’ed together in pairs. The output from only one of a wire-OR’ed
pair should be enabled at any given time. The device program-
ming software must be properly written to cause this to happen.
At some point, the number of outputs that are wire-OR’ed becomes
too great to maintain system performance. This varies according
to which system specifications are most important. It also
depends on whether the matrix consists of AD8106s or AD8107s.
The output disabled impedance of the AD8106 is much
higher than that of the AD8107. As a result, its disabled
parasitics have a smaller effect on the one output that is
enabled. For example, a 128 × 5 crosspoint can be created
with eight AD8106s/AD8107s. This design has 128 separate
inputs and the corresponding outputs of each device wire-
OR’ed together in groups of eight.
Using additional crosspoint devices in the design can lower the
number of outputs that must be wire-OR’ed together. Figure 47
shows a block diagram of a system using eight AD8106s and
two AD8107s to create a nonblocking, gain-of-two, 128 × 5
crosspoint that restricts the wire-OR’ing at the output to only
four outputs.
Additionally, by using the lower four outputs from each of the
two Rank 2 AD8107s, a blocking 128 × 10 crosspoint array can
be realized. There are, however, some drawbacks to this technique.
The offset voltages of the various cascaded devices accumulate
and the bandwidth limitations of the devices compound. The
extra devices also consume more current and take up more
board space. Once again, the overall system design specifica-
tions determine which tradeoffs should be made.
