M52775FP
VIF, SIF, VIDEO, CHROMA, DEFLECTION FOR NTSC
DESCRIPTION
The M52775FP is desinged to provide a solution to NTSC color
television system. It is an I2C bus controlled NTSC 1 chip. It consists
of various processing blocks such as video IF, sound IF, luminance,
chrominance, mono-sound, OSD display, interface, H and V
deflection. At each block, I2C control is possible and a total of 30
parameters can be controlled by I2C bus.
