ZL50074GAC ZARLINK [Zarlink Semiconductor Inc], ZL50074GAC Datasheet - Page 34

• Manufacturer Part Number: ZL50074GAC
• Description: 32 K x 32 K Channel TDM Switch with 128 Input and 128 Output Streams
• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

Within each stream group, the mapping of each of the actual output streams, SToAn, SToBn, SToCn and SToDn,
depends on the device data rate programmed into the Global Rate Control Register. The address offsets to these
control areas for each of the output streams are illustrated in Table 17.
12.2
The data memory field is a read only address range used to monitor the data being received by the input streams.
Addressing into each of the streams is illustrated in Table 18.
