LA7806

B/W TV Synchronization, Deflection Circuit

Overview Package Dimensions

The LA7806 is a multifunctional integrated circuit which unit:mm
is based on the internal circuit of the LA7800, incorporates 3006B-DIP16
various functions required for synchronization and deflec-
[LA7806]
tion circuits of monochromatic television set, and operates

Functions SANYO : DIP16
• Synchro separator. • Horizontal oscillator.
• Horizontal AFC. • Vertical oscillator.
• Vertical driver. • Vertical blanking pulse making.

Features
• Multifunction and small-size (DIP-16).
• Minimum number of parts required.
• Horizontal and vertical oscillators being stable to varia-
tion of ambient temperature and supply voltage owing to
small warming-up drift.
• Small variation of horizontal oscillation frequency.
• Good linearity and interlace owing to DC bias at vertical
output stage being sampling controlled within retrace
time.
• Vertical blanking pulse width being freely set up accord-
ing to peripheral parts.

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

Sample Application Circuit

Note) 1. The vertical output circuit is shown by the basic circuit.

2. The peripheral parts at pin 8 should be changed in accordance with the Ver. Out circuit conditions.
3. The limiting resistor (220Ω : 1Vp-p) at pin 14 should be changed in proportion to the magnitude of the input
video signal.
4. In the time constant circuit (120kΩ, 4.7µF) at pin 14, the time constant should be changed by changing the
resistance value in accordance with the DC level of the input video signal and then by changing the capaci-
tance value.
