DISTRIBUTED-LOAD BACKPLANE SWITCHING CHARACTERISTICS
This data sheet is specified for and tested to the lump load shown in Figure 1. However, the designer probably uses
this GTLP device in a distributed load like that shown in Figure 2, in which actual B-port backplane switching
characteristics are different. Therefore, the device is modeled as shown in Figure 3, which very closely matches the
results obtained using Figure 2. Switching characteristics based on Figure 3 more closely match actual backplane
design requirements.
