描述 Description

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 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.
