| MITSUBISHI ICs (TV) PRELIMINARY Notice:This is not a final specification. Some parametric limits are subject to change. 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 bus. A baseband 1H delay line is built-in, and conjunction with SECAM decoder M52325AP simplifies multi system CTV chassis.
