Bidirectional and Unidirectional Switching Applications
The MT90869 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 16.384Mb/s and
64 output streams (32 backplane, 32 local) at 16.384Mb/s.
One typical mode of operation is to separate the Backplane and Local sides, as shown in Figure 3 below.
Figure 3 - 8,192 x 8,192 Channels (16Mb/s), Bidirectional 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, i.e.: Backplane input to Local output switching.
Often a system design does not need to differentiate between a Backplane and Local side, and merely needs
maximum switching capacity. In this case, the MT90869 can be used as shown in Figure 4 to give the full 16,384
x 16,384 channel capacity.
Figure 4 - 16,384 x 16,384 Channels (16Mb/s), Unidirectional Switching
In this system, the Backplane and Local inputs and outputs are combined so that the switch appears as a 64 stream
input by 64 stream output switch. This style of operation is similar to older switch designs, such as the MT90826.
Note, in either configuration the Backplane may be operated in the 32Mb/s Mode, providing 512 channels on each
of the 16 available input and output streams (BSTi0-15 and BSTo0-15) operating at a data-rate of 32.768Mb/s, in
conjunction with the Local streams (LSTi0-31 and LSTo0-31) operated at 16.384Mb/s. This allows data-rate
conversion between 32.768Mb/s and 16.384Mb/s without loss to the switching capacity.
