M52335SP
NTSC SYSTEM SINGLE-CHIP COLOR TV SIGNAL PROCESSOR
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.

Large-scale single-chip integration provides set rationalization,
high reliability and less power dissipation.
P LL-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
horizontal frequency oscillator using a ceramic oscillator,
requiring no adjustment of horizontal free run frequency.
Vertical oscillator is obtained by counting down double horizontal
frequency oscillator generated by 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 black expansion circuit
Built-in Y-delay line circuit.
Built-in on-screen character display circuit.
DC voltage control is applied to picture quality, contrast,
luminance, color saturation, tint and sound volume.
