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 customers
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 customers products or equipment.
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.
In the event that any and all SANYO products described or contained herein fall under strategic
products (including services) controlled under the Foreign Exchange and Foreign Trade Control Law of
Japan, such products must not be exported without obtaining export license from the Ministry of
International Trade and Industry in accordance with the above law.

Overview
The LC78681KE and LC78681KE-L are signal processing and servo control CMOS LSIs for compact disk players, laser disk players, CD-V, CD-I and similar applications. These products provide a rich set of signal processing functions, including demodulation of the EFM signal from the optical pickup, de-interleaving, error detection and correction, and digital filter functions that can contribute to end product cost reduction. These LSIs also process servo system commands sent from a control microprocessor. They can be directly interfaced to a serial input DAC (such as the Sanyo LC78835K or LC78855K) that provides built-in dedicated digital filters.
