IP3338CX24

10-channel integrated LC-filter network with ESD input protection

7.2 Crosstalk

The setup for measuring crosstalk in a 50

Ω system is shown in Figure 5.

The crosstalk between adjacent channels within the IP3338CX24 for different channel

pairs measured in a 50

Ω NetWork Analyzer (NWA) system, is shown in Figure 6. In all

cases, all unused connections are terminated with 50

Ω to ground.

(1) Channel 1 (pins A2 and A5).

(2) Channel 9 (pins E2 and E5).

(3) Channel 4 (pins B1 and B4).
