Figure 4 shows typical Insertion Loss graphs for the PACS1284-06 for Data and Strobe signals. The curves are

dependent on the physical location of the filter elements with respect to the ground and V

These graphs are measured in a 50 Ohm environment. The signal is introduced at the series resistor input and the

output is measured at the corresponding filter capacitor. The graphs labeled A,B, and C are measured between 14

(input) and 16 (output), pin 3 (input) and 26 (output), and pin 6 (input) and 23 (output), respectively. The A graph

depicts “worst case” filter performance, while C represents a “best case” situation. Graphs of all other filter elements

will fall in between these two.
