• Manufacturer Part Number: ZL50052GAC
• Description: 8 K Channel Digital Switch with High Jitter Tolerance, Single Rate (32 Mbps), and 16 Inputs and 16 Outputs
• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

In this system, the Backplane and Local input streams are combined, and the Backplane and Local output streams
are combined, so that the switch appears as a 16 input stream by 16 output stream switch. This gives the maximum
8,192 x 8,192 channel capacity.
Often a system design needs to differentiate between a Backplane and a Local side, or it needs to put the switch in
a bi-directional configuration. In this case, the ZL50052 can be used as shown in Figure 4 to give 4,096 x 4,096
channel bi-directional capacity.
In this system setup, the chip has a capacity of 4,096 input channels and 4,096 output channels on the Backplane
side, as well as 4,096 input channels and 4,096 output channels on the Local side. Note that some or all of the
output channels on one side can come from the other side, e.g., Backplane input to Local output switching.
1.1
The ZL50052 can be configured as an 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 3.

1.1.2
Another typical application is to configure the ZL50052 as a non-blocking 4 K by 4 K bi-directional switch, as
shown in Figure 4:
