Shown on this slide is another real world design/application example with both the 9X442SL and 9X440SL being used in a 4G LTE base station application with the popular Cavium Octeon II SOC CPU family. The USB 2.0 hubs are used for debug, software upload, KVA, and error logging as part of tower transmitter equipment maintenance. Similar to the previous examples, the Octeon II processor family also has no USB 2.0 ports. The 9X442 and 9X440 provide the needed USB 2.0 port fanout not provided by the SOC IC.
