Monolithic Triple 9.5 Ns CRT Driver [Obsolete]

Once the optimum values are determined. Note that the components are placed so. To prevent this, leads to the video amplifier input circuit should be shielded, and input cir- cuit wiring should be spaced as far as possible from output circuit wiring. Ferrite core inductors from J.

The fall time shows a. The diode placement and routing is very important for minimizing the voltage 5 www.

The NSC demo board also has a position open to add a resistor in parallel with L1. This minimizes parasitic capacitance in the video path and also enhances the effectiveness of the pro- tection diodes. The IC is packaged in an industry standard 9-lead TO Also, the length of the signal traces from the preamplifier to the LM and from the LM to the CRT cathode should be as short as pos- sible. See Thermal Considerations section.

The rise time shows a maximum variation relative to the cen. The figure shows that the rise time of the LM increases. Once the optimum values are determined the variable resistors can be replaced with fixed values. It is very important to use induc- tors with very high self-resonant frequencies, preferably above MHz. Increasing the values of R1. This resistor can be used to help control overshoot.
