MITSUBISHI M52770ASP

MITSUBISHI ICs (TV)
M52770ASP
NTSC/PAL TV SIGNAL PROCESSOR
DESCRIPTION
The M52770ASP is a single chip CTV processor which has
PIN CONFIGURATION (TOP VIEW)
VIF/SIF, luminance, chrominance, mono sound, OSD display,
RGB interface, and deflection.
I2C
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.
