Unidirectional and Bi-directional Switching Applications
The ZL50062/64 has a maximum capacity of 16,384 input channels and 16,384 output channels. This is calculated
from the maximum number of streams and channels: 64 input streams (32 Backplane, 32 Local) at 16.384Mbps
and 64 output streams (32 Backplane, 32 Local) at 16.384Mbps.
A typical mode of operation is to separate the input and output streams to form a unidirectional switch, as shown in
Figure 4 below.
Figure 4 - 16,384 x 16,384 Channels (16Mbps), Unidirectional Switching
In this system, the Backplane and Local input streams are combined, and the Backplane and Local output streams
are combined, so that the switch appears as a 64 input stream by 64 output stream switch. This gives the maximum
16,384 x 16,384 channel capacity.
Often a system design needs to differentiate between a Backplane and a Local side, or it needs to put the switch in
a bi-directional configuration. In this case, the ZL50062/64 can be used as shown in Figure 5 to give 8,192 x 8,192
channel bi-directional capacity.
Figure 5 - 8,192 x 8,192 Channels (16Mbps), Bi-directional Switching
In this system setup, the chip has a capacity of 8,192 input channels and 8,192 output channels on the Backplane
side, as well as 8,192 input channels and 8,192 output channels on the Local side. Note that some or all of the
output channels on one side can come from the other side, e.g., Backplane input to Local output switching.
