All rise or fall times measured using source with 0 V to 3 V steps, 10 % to 90 %.
Performed on all high speed lines (channels including R1 to R9, see Figure 2 ).
8. Application information
8.1 Insertion loss
The insertion loss measurement con?guration of a typical NetWork Analyzer (NWA)
system is shown in Figure 3 . The insertion loss is measured with a test PCB utilizing laser
drilled micro-via holes that connect the PCB ground plane to the IP4350CX24 ground
pins.
