Figure 1-18. Serial DSL Configurations
1.12.4.2
The UTOPIA mode applications are similar to the serial mode but the serial clocks are not typically used (or always
available). In UTOPIA mode, the M28529 device only has the SPRxClk[23:0] inputs available for those applications
that can take advantage of them. As noted, these aren’t typically used.
1.12.4.2.1
The T1/E1 UTOPIA application is shown in
the M28529 device. Since the device does not provide 32 serial clocks, the IMA function most often is configured to
use its internal clock synthesizers when operating in the “Slave / External” configuration. This approach is used
when operating in fractional T1/E1 applications.
