M52771ASP

NTSC/PAL TV SIGNAL PROCESSOR

DESCRIPTION

The M52771ASP is a single chip CTV processor which has

VIF/SIF, luminance, chrominance, mono sound, OSD display,

RGB interface, and deflection.

And it is possible to control each parameters by I2C bus. A

baseband 1H delay line is built-in, and conjunction with SECAM

decoder M52325AP simplifies multi system CTV chassis.

FEATURES

• Built-in 1H Delay Line using Bi-CMOS technology

• Multistandard PLL demodulator for IF

• Alignment-free sound demodulator

• Flexible source selection with internal CVBS and external CVBS

or Y/C input signal

• Audio switch integrated

• Integrated chroma trap and bandpass filters with auto-calibration

• Luminance delay line integrated

• RGB control circuit with cut-off and drive

• Linear RGB inputs and fast blanking

• Horizontal synchronaization with two control loops and alignment-

free H-oscillator

• Vertical count-down circuit

• Vertical saw tooth generator integrated

• I2C Bus control of various functions

• Easy interfacing with SECAM decoder for multistandard

applications

• Small amount of peripheral components

• 52 pin shrink DIP
