8.2.4 Application Performance Plots
Depending on the selected input, the LMH1219 performance was measured with the test setups shown in Figure 23 and Figure 24.
Figure 23. Test Setup for LMH1219 Cable Equalizer (IN0+) 
Figure 24. Test Setup for LMH1219 PCB Equalizer (IN1±) The eye diagrams in this subsection show how the LMH1219 improves overall signal integrity in the data path for 75-Ω coax cable input length (CC) when IN0 is selected and 100-Ω differential FR4 PCB trace when IN1 is selected.
