1.1.3
The ZL50052 can be configured as a blocking bi-directional switch if it is an application requirement. For example,
it can be configured as a 6 K by 2 K bi-directional blocking switch, as shown in Figure 5:

2.1
The device supports five switching configurations:
1. Unidirectional switch
2. Backplane-to-Local
3. Local-to-Backplane
4. Backplane-to-Backplane
5. Local-to-Local
The following sections describe the switching paths in detail. Configurations (2) - (5) enable a non-blocking
bi-directional switch with 4,096 Backplane input/output channels at Backplane stream data rates of 32.768 Mbps,
and 4,096 Local input/output channels at Local stream data rates of 32.768 Mbps. The switching paths of
configurations (2) to (5) may be operated simultaneously.
2.1.1
The device can be configured as a 8,192 x 8,192 unidirectional switch by grouping together all input streams and all
output streams. All streams operate at a data rate of 32.768 Mbps.
2.1.2
The device can provide data switching between the Backplane input port and the Local output port. The Local
Connection Memory determines the switching configurations.
6,144 channel x 2,048 channel blocking switching from Backplane input to Local output streams
2,048 channel x 6,144 channel blocking switching from Local input to Backplane output streams
6,144 channel x 6,144 channel non-blocking switching from Backplane input to Backplane output streams
2,048 channel x 2,048 channel non-blocking switching from Local input to Local output streams
Total 12 streams input and 12 streams output
