zl50058 Zarlink Semiconductor, zl50058 Datasheet - Page 22

• Manufacturer Part Number: zl50058
• Description: 12 K Channel Digital Switch With High Jitter Tolerance, Per Stream Rate Conversion 2, 4, 8, 16 Or 32 Mbps , 48 Input And 48 Output Streams
• Manufacturer: Zarlink Semiconductor

The modes in which one port operates in 32 Mbps Mode while the other port operates in Non-32 Mbps Mode allow
data rate conversion between 32.768 Mbps and 16.384 Mbps without loss to the switching capacity.
1.1
The ZL50057/8 can be configured as a 12 K by 12 K non-blocking unidirectional digital switch, a 6 K by 6 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 ZL50057/8 as a non-blocking 6 K by 6 K bi-directional switch, as
shown in Figure 6:

1.1.3
The ZL50057/8 can be configured as a blocking bi-directional switch if it is an application requirement. For
example, it can be configured as an 8 K by 4 K bi-directional blocking switch, as shown in Figure 5:
