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.

Note) 1. The vertical output circuit is represented by the basic circuit.
2. The peripheral parts connected to pin 8 are changed according to the Ver. Out circuit conditions.
3. The limit resistor (220Ω : 1Vp-p) connected to pin 14 is changed according to the magnitude of the input
video signal.
4. The time constant circuit (120kΩ, 4.7µF) connected to pin 14 is such that the resistor is changed according to
the DC level of the input video signal and the time constant is changed with the capacitance value.
