Multi channel LC-filter network for high-speed data interfaces

7.2 Crosstalk

The crosstalk measurement configuration of a typical 50

Ω NetWork Analyzer (NWA)

system for evaluation of the IP3348CX5, IP3348CX10, IP3348CX15 and IP3348CX20 is

shown in Figure 8.

Four typical examples of crosstalk measurement results of IP3348CX15 are depicted.

Unused channels are terminated with 50

Ω to ground.
