• Manufacturer Part Number: zl50064
• Description: 16 K Channel Digital Switch With High Jitter Tolerance, Single Rate 2, 4, 8 Or 16 Mbps And 64 Input And 64 Output Streams
• Manufacturer: Zarlink Semiconductor

1.1
The ZL50062/64 can be configured as a 16K by 16K non-blocking unidirectional digital switch, an 8K by 8K
non-blocking bi-directional digital switch, or as a blocking switch with various switching capacities.
1.1.1
Because the input and output drivers are synchronous, the user can combine input Backplane streams and input
Local streams as well as output Backplane streams and output Local streams to increase the total number of input
and output streams of the switch in a unidirectional configuration, as shown in Figure 4.

1.1.2
Another typical application is to configure the ZL50062/64 as a non-blocking 8K by 8K bi-directional switch, as
shown in Figure 5:

1.1.3
The ZL50062/64 can be configured as a blocking bi-directional switch if it is an application requirement. For
example, it can be configured as a 12K by 4K bi-directional blocking switch, as shown in Figure 6:
