M52771SP
NTSC/PAL TV SIGNAL PROCESSOR
DESCRIPTION
The M52771SP is a single chip CTV processor which has VIF/SIF,
luminance,
chrominance,
mono
sound,
OSD
display,
PIN CONFIGURATION (TOP VIEW)
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
