Figure 30. PE-33016 Used to Provide 16 Dual Outputs.
In the splitting application, a port expander can be used to provide dual
outputs in groups of 16 outputs. Use the PE33016 Port expander for HD
operations and the PE2x2-3G Port expander for 3Gp/s operations. All
outputs are non-inverting. For example, a 256 x 256 router could be
arranged as follows:
• 256 inputs x 240 single outputs and 16 dual outputs - uses 1 Port
expander, or
• 256 inputs x 224 single outputs and 32 dual outputs - uses 2 Port
expander, or
• 256 inputs x 208 single outputs and 48 dual outputs - uses 3 Port
expander... etc.
Figure 31 shows a router with 240 single outputs and 16 dual outputs. In
the figure below, the PE33016 Port expander is used as an example.
