Duplication and Expansion
Possible expanded configurations include:
• 1024 inputs x 512 dual outputs
• 1024 inputs x 1024 dual outputs
• 512 inputs x 1024 outputs
• 2048 inputs x 2048 outputs (SD and HD only)
• 1024 inputs x 1024 outputs
Some of these configurations are shown on the following pages. Notice that
the same port expander type is used for both downstream combining (for
input expansion) and upstream splitting (for output expansion). All
outputs are non-inverting. In the figures below the PE33016 Port expander
is used as an example. Use the PE33016 Port expander for HD operations
and the PE2x2-3G Port expander for 3Gp/s operations.
