Application Hints
(Continued)
provides a good example of a layout that can be used as a
guide for future layouts. Note the location of the following
components:
C19—V
bypass capacitor, located very close to pin 4
and ground pins
C20—V
BB
bypass capacitors, located close to pin 8 and
ground
C46, C47, C48—V
bypass capacitors, near LM2463
and V
CC
clamp diodes. Very important for arc protection.
The routing of the LM2463 outputs to the CRT is very critical
to achieving optimum performance. Figure 13 shows the
routing and component placement from pin 1 of the LM2463
to the blue cathode. Note that the components are placed so
that they almost line up from the output pin of the LM2463 to
the blue cathode pin of the CRT connector. This is done to
minimize the length of the video path between these two
components. Note also that D8, D9, R24 and D6 are placed
to minimize the size of the video nodes that they are at-
tached to. This minimizes parasitic capacitance in the video
path and also enhances the effectiveness of the protection
diodes. The anode of protection diode D8 is connected
directly to a section of the the ground plane that has a short
and direct path to the LM2463 ground pins. The cathode of
D9 is connected to V
very close to decoupling capacitor
C48 (see Figure 13) which is connected to the same section
of the ground plane as D8. The diode placement and routing
is very important for minimizing the voltage stress on the
LM2463 during an arcover event. Lastly, notice that S3 is
placed very close to the blue cathode and is tied directly to
CRT ground.
