Applications
Switch Matrix Architectures
The MT90823 is an ideal device for medium to large size switch matrices where voice and grouped data channels
are transported within the same frame. In such applications, the voice samples have to be time interchanged with a
minimum delay while maintaining the integrity of grouped data. To ensure the integrity of grouped data during
switching and to provide a minimum delay for voice connections, the MT90823 provides per-channel selection
between variable and constant throughput delay. This can be selected by the V/C bit of the Connection Memory.
Figure 6 illustrates how four MT90823 devices can be used to form non-blocking switches for up to 4096 channels
with data rate of 8.192 Mb/s.
Serial Input Frame Alignment Evaluation
The MT90823 is capable of performing frame alignment evaluation. The frame pulse under evaluation is connected
to the FE (frame measurement) pin. An external multiplexer is required to select one of the frame pulses related to
the different input streams. Figure 7 - The block diagram at Figure 7 shows a switch matrix that performs frame
alignment evaluation for 16 frame pulses.
