M65580MAP-XXXFP

Digital Video/Chroma/Deflection+MCU

[ASIC Block]

Description

CVBS(TV/EXT) signals or Y/C signals input to this IC are converted to 8 bit digital signal by 2 channels high speed video

ADCs. These signals are input to digital section to obtain high performance R/G/B signals. First, CVBS signals are separated

to high quality Y/C signals by 2 dimensional adaptive YC separation circuit, and then Y/C signals are converted to R-Y&B-Y

signals by digital chroma decoder, after that, to R/G/B signals by RGB matrix circuit. These signals are mixed with OSD

signals come from MCU block, are converted to analog R/G/B signals by 3 channel 10 bit high speed video DACs. In

deflection block, to get a better Horizontal & Vertical signals, a conventional analog solution by analog CMOS technology is

used.

ASIC block consists of the followings 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.
