Description
The M52771ASP is a single chip CTV processor with 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.
