• Manufacturer Part Number: zl50075
• Description: 32 K Channel Digital Switch With High Jitter Tolerance, Rate Conversion Per Group Of 2 Streams 8, 16, 32 Or 64 Mbps , And 64 Inputs And 64 Outputs
• Manufacturer: Zarlink Semiconductor

Within each stream group, the mapping of each of the actual output streams, SToAn and SToBn, depends on the
output rate programmed into the Group Control Registers. The address offsets to these control areas for each of
the output streams are illustrated in Table 16.
