DESCRIPTIO N
The TDA9102F is a monolit hic integrated c ircuit for
horizontal and vertical sync processing in monochrome and color video displays driven by input
TTL compatible signals.
The TDA9102F is supplied in a 20 pin dual in line
package with pin 1 1 connected to ground and used
for heatsinking.

Technical note 4
The second PLL can recover the storage of horizontal output stage maintaining a constant duty
cycle till the trailing edge of the output pulse gets
the trailing edge of the flyback pulse. From this
point on, only the leading edge of the output pulse
will be shifted covering a total phase shift of: 0.30T ;
overcoming this value, it will produce a notch in the
output pulse (@ f
= 27kHz).

Technical note 5
The voltage reference at Pin 19 can be used to
polarize the DC operating point of the vertical
9102F-03.EPS
booster. This v oltage corres p onds to the double of
the mean value voltage of the vertical sawtooth at
Pin 13.

Remark: The value of C2 influences the horizontal

the relative pull-in range. If the horizontal frequency is changed by using R1, the pull-in range
changes accordingly with the formula (A).
