Features: • Y/C processor : 8bit Input, 10bit Output digital processing
• Deflection processor : optimized system by conventional analog and digital mixed solution
• ADC&DAC : 8bit high speed video ADC & 10bit high speed video DAC
[MCU Block]
MCU(single microcomputer) in this IC has almost same function and performance as M37272MA-XXXSP/FP in mass-production.
And it is operated by simple instruction in the same memory space as that of built-in ROM, RAM, I/O.
It has a OSD, data slicer , and I2C-BUS interface. So it is very useful for a channel selection system for NTSC TV with a closed caption decoder.
[ASIC Block]
ASIC block consists of the following blocks.
(1) Analog frontend block ; Analog SW(2 CVBS(TV&EXT) inputs, Y/C signals to one signal, 2 channels 8 bit high speed video ADCs,and ACC amplifiers
(2) Video and Chroma block ; A high performance 2 line adaptive YC separation by 1 line memory, Video blocks including sharpness,YNR, a high performance blackstretch circuits, Chroma decoder, and RGB matrix including OSD mixing circuit.
(3) Deflection block ; A high performance sync separation by analog and digital mixed solution
(4) Analog backend block ; 3 channels 10 bit high speed video DACs for Cutoff & Drive, and Mute circuit.

DescriptionThe M65580MAP-XXXFP are semiconductor integrated circuits designed with CMOS silicon gate technology for NTSC television system, include 8bit MCU( M37272MA core) with a closed caption decoder and circuits needed for TV baseband signals(Video and Chroma) processor and Deflection in a chip. PCB area and EMI noise can be reduced by one chip and 80QFP, and internal connection of OSD signals. And it can realize a adjustment free system by built-in MCU and get a high performance adaptive YC separation by 1 line memory. The above technology makes its performance more stable and better.
