GENERAL DESCRIPTION
The TEA2031A is intended to provide to 110° color
TV sets a parabolic and keystone frame rate mod-
ulated correction in addition to the main horizontal
scanning.
A stable 6.3V internal reference provides current
and voltage references to the whole IC.
Pins 1 and 2 are two symmetrical inputs of an on-
chip multiplier circuit and are internally held at
6.3V reference potential level. Current inputs to
these pins are drawn from external sources via ap-
propriate resistors. The frame saw-tooth wave-
form which has a peak-to-peak value of around 3
volts and a mean value of about 2.5 volts, supplies
