• Manufacturer Part Number: ZL50051
• Description: 8 K Channel Digital Switch with High Jitter Tolerance, Single Rate (8 or 16 Mbps), and 64 Inputs and 64 Outputs
• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

1.1
The ZL50051/3 can be configured as a 8 K by 8 K non-blocking unidirectional digital switch, a 4 K by 4 K
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 ZL50051/3 as a non-blocking 4 K by 4 K bi-directional switch, as
shown in Figure 5:

1.1.3
The ZL50051/3 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 6:
