Description
The M65580MAP-XXXFP are semiconductor integrated circuits designed with CMOS silicon gate technology for
NTSC television system, include 8 bit MCU (M37272MA core) with a closed caption decoder and circuits needed for
TV base-band 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 an 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.
Features
•
Y/C processor:
8 bit Input, 10 bit Output digital processing
•
Deflection processor: optimized system by conventional analog and digital mixed solution
•
ADC & DAC:
8 bit high speed video ADC & 10 bit 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 an OSD, data slicer, and I
2
C-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 front-end 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 black-stretch 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.
Application
NTSC TV with a closed caption decoder
