Notes on PWB Pattern Design
x In an ideal design, power supply and ground lines will be provided separately for each system to minimize the influence of
x Power supply and ground lines must be made as wide and as short as possible, and the impedance to high frequencies must

during the design phase. This IC is a special-purpose device for use in CD players, and its specifications differ from those of
standard logic ICs and other general-purpose products. Also note that, depending on the application, failsafe measures and/or
system level debugging of the total system may be required as well.

be made as low as possible. Decoupling capacitors (consisting of two capacitors: one about 0.01 to 1.0 µF and another about
100 to 220 µF) should be inserted between each power supply pin and ground. Note, however, that if this capacitance is too
large, it may result in latchup problems.

semiconductor products fail with some probability. It is possible that these probabilistic failures could give
rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that
could cause damage to other property. When designing equipment, adopt safety measures so that these
kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits
and error prevention circuits for safe design, redundant design, and structural design.
