Monolithic Linear IC
LA7800
Color TV Synchronization, Deflection Circuit
Overview
The LA7800 is a multifunctional IC containing various
functions required for synchronization, deflection of color
television sets. This IC has been developed under the de-
sign concept that the basic characteristics should be made
more complete and the television sets with this IC incorpo-
rated should be streamlined by making the device compact
(DIP-16) and by minimizing the number of parts required.

Functions
• Synchonizing separation.
• Horizontal oscillation.
• Vertical drive.
• Vertical blanking.
• Horizontal AFC.
• Vertical oscillation.
• X-ray protection.
Features
• Multifunction and compact (DIP-16).
• Minimum number of parts required.
• Horizontal and vertical oscillators are stable against varia-
tions in ambient temperature and supply voltage due to
small warm-up drift.
• Small variation in horizontal oscillation frequency.
• Good linearity and interlace because DC bias at vertical
output stage is subjected to sampling control within re-
trace time.
• Vertical blanking pulse width can be set freely according
to peripheral parts.

the customer should always evaluate and test devices mounted in the customer's 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.
