PACS1284
Performance Information
Filter Capacitors
Figure 1
shows typical insertion loss graphs for the
PACS1284, for Data and Strobe signals. The curves
are dependent on the physical location of the filter ele-
ments with respect to the ground and V
CC
terminals of
the device.
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 three plotted lines in
Figure 1
depict the following
measurements:
Line labeled "A" is measured between pin 14
(input) and pin 16 (output).
Line labeled "B" is measured between pin 3 (input)
and pin 26 (output).
Line labeled "C" is measured between pin 6 (input)
and pin 23 (output).
The "A" graph depicts “worst case” filter performance,
while "C" represents a “best case” situation. Graphs of
all other filter elements will fall between these two. (The
filter insertion loss was measured using a Hewlett
Packard HP8753C Analyzer.)
