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 design concept that the basic characteristics should be made more complete and the television sets with this IC incorporated 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 retrace time. Vertical blanking pulse width can be set freely according to peripheral parts.
