PC BOARD LAYOUT CONSIDERATIONS
For optimum performance, an adequate ground plane, iso-
lation between channels, good supply bypassing and mini-
mizing unwanted feedback are necessary. Also, the length of
the signal traces from the preamplifier to the LM2436 and
from the LM2436 to the CRT cathode should be as short as
possible. The following references are recommended:
Ott, Henry W., “Noise Reduction Techniques in Electronic
Systems”, John Wiley & Sons, New York, 1976.
“Video Amplifier Design for Computer Monitors”, National
Semiconductor Application Note 1013.
Pease,
Robert A.,
“Troubleshooting Analog
Circuits”,
Butterworth-Heinemann, 1991.
Because of its high small signal bandwidth, the part may
oscillate in a monitor if feedback occurs around the video
channel through the chassis wiring. To prevent this, leads to
the video amplifier input circuit should be shielded, and input
circuit wiring should be spaced as far as possible from output
circuit wiring.
NSC DEMONSTRATION BOARD
Figure 12 shows the routing and component placement on
the NSC LM1279/2436 demonstration board. The schematic
of the board is shown in Figure 11. This board provides a
good example of a layout that can be used as a guide for
future layouts. Note the location of the following compo-
nents:
C55—V
CC bypass capacitor, located very close to pin 4
and ground pins
C43, C44 — V
BB bypass capacitors, located close to pin 8
and ground
C53–C56 — V
CC bypass capacitors, near LM2436 and
V
CC clamp diodes. Very important for arc protection.
The routing of the LM2436 outputs to the CRT is very critical
to achieving optimum performance. Figure 13 shows the
routing and component placement from pin 1 of the LM2436
to the blue cathode. Note that the components are placed so
that they almost line up from the output pin of the LM2436 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 D14, D15, R29 and D13 are
placed to minimize the size of the video nodes that they are
attached to. This minimizes parasitic capacitance in the
video path and also enhances the effectiveness of the pro-
tection diodes. The anode of protection diode D14 is con-
nected directly to a section of the the ground plane that has
a short and direct path to the LM2436 ground pins. The
cathode of D15 is connected to V
CC very close to decoupling
capacitor C55 (see Figure 13) which is connected to the
same section of the ground plane as D14. The diode place-
ment and routing is very important for minimizing the voltage
stress on the LM2436 during an arcover event. Lastly, notice
that S3 is placed very close to the blue cathode and is tied
directly to CRT ground.
