Data Sheet
10
Zarlink Semiconductor Inc.
2.1.4
Local-to-Local path
The device can provide data switching between the Local input and output ports. The Local Connection
Memory determines the switching configurations.
2.1.5
Uni-directional Switch
The device may be optionally configured to provide an 8,192 x 8,192 uni-directional switch by grouping
together all input and all output streams. All streams (LSTi/LSTo0-15 and BSTi/BSTo0-15) may be operated at
a data-rate of 16.384Mb/s. Lower data-rates may be employed with a corresponding reduction in switch
capacity.
2.2
Port Data Rate Modes and Selection
The selection of individual stream data-rates is summarized in Table 1.
2.2.1
Local Port Rate Selection
The Local port has 16 input (LSTi0-15) and 16 output (LSTo0-15) data streams. All input and output streams
may be individually selected for operation at a data rate of either 2.048Mb/s, 4.096Mb/s, 8.192Mb/s or
16.384Mb/s. The timing of the input and output clocks and frame pulses are shown in Figure 6, Local Port
Timing Diagram for 2,4,8 and 16Mb/s stream rates.
2.2.1.1
Local Input Port
The bit rate for each input stream is selected by writing to a dedicated Local Input Bit Rate Register (LIBRR0-
15). Refer to Table 38, Local Input Bit Rate Register (LIBRRn) Bits.
Stream Number
Rate Selection Capability
(for each individual stream)
Input stream - Local 0-15 (LSTi0-15)
2.048, 4.096, 8.192 or 16.384Mb/s
Output stream - Local 0-15 (LSTo0-15)
2.048, 4.096, 8.192 or 16.384Mb/s
Input stream - Backplane 0-15 (BSTi0-15)
2.048, 4.096, 8.192 or 16.384Mb/s
Output stream - Backplane 0-15 (BSTo0-15)
Table 1- Per-stream Data-Rate Selection: Backplane and Local streams
2.048, 4.096, 8.192 or 16.384Mb/s
