DESCRIPTION
The M52335SP is a semiconductor integrated circuit thatintegrates
NTSC system color TV signal processing functions into a single
chip. It contains video IF, sound IF, picture, color, on-screen
character display and deflection signal processing functions.
Combining the IC with a simple output stage using a tuner and
transistors provides rational NTSC system color TV set design.
FEATURES
Large-scale single-chip integration provides set rationalization,
high reliability and less power dissipation.
PLL
-employed full sync detector circuit is used as a video detector
circuit to improve characteristics such as DG, DP, 920kHz beat
and cross color.
A quadrature detector circuit is used as a sound IF FM detector
to simplify external circuits and improve linearity.
Coilless AFT.
Horizontal oscillator is obtained by counting down from x32
horizontalfrequency oscillatorusing aceramicoscillator,
requiring no adjustment of horizontal free run frequency.
Vertical oscillator is obtained by counting down double horizontal
frequency oscillatorgeneratedby horizontal count-down,
requiring no vertical sync adjustment. Using a 2-wind system
provides high noise resistance capability.
Double AFC is used as a horizontal circuit to reduce horizontal
jitter in a weak electric field and screen distortion caused by
luminance change.
Also, the sync detector circuit allows use as a detector signal as
for sound muting or automatic tuning.

Built-in Y-delay line circuit.
Built-in on-screen character display circuit.
