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.

FEATURES
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 resista...
