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

shared impedances.

x Power supply and ground lines must be made as wide and as short as possible, and the impedance to high frequencies must

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.

Other Notes

If you have any questions or if anything is even slightly unclear, please contact your SANYO sales or technical representative

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.

Q Specifications of any and all SANYO products described or contained herein stipulate the performance,

characteristics, and functions of the described products in the independent state, and are not guarantees

of the performance, characteristics, and functions of the described products as mounted in the customer’s

products or equipment. To verify symptoms and states that cannot be evaluated in an independent

device, the customer should always evaluate and test devices mounted in the customer’s products or

equipment.

Q SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all

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.

Q In the event that any or all SANYO products (including technical data, services) described or contained

herein are controlled under any of applicable local export control laws and regulations, such products

must not be exported without obtaining the export license from the authorities concerned in accordance

with the above law.
