1.4 Oscillator concerns
Figure 1.4.1. Wiring for a large current signal line
Figure 1.4.2. Wiring of signal lines where potential levels change frequently
Take care to prevent an oscillator that generates clocks for a microcomputer operation from being affected
by other signals.
1.4.1 Keeping oscillator away from large current signal lines
1.4.2 Installing oscillator away from signal lines where potential levels change frequently
Install a microcomputer (and especially an oscillator) as far as possible from signal lines where a current
larger than the tolerance of current value flows.
In the system using a microcomputer, there are signal lines for controlling motors, LEDs, and thermal
heads or others. When a large current flows through those signal lines, strong noise occurs because of
mutual inductance.
Install an oscillator and a connecting pattern of an oscillator away from signal lines where potential levels
change frequently. Also, do not cross such signal lines over the clock lines or the signal lines which are
sensitive to noise. Or do not stretch long such signal lines parallelly to these said lines.
Signal lines where potential levels change frequently (such as the TA
lines at signal rising edge or falling edge. If such lines cross over a clock line, clock waveforms may be
deformed, which causes a microcomputer failure or a program runaway.
