Digital Video/Chroma/Deflection+MCU

Function and Outline of ASIC Block

Chip

Power down mode : 3 modes [ PD0 & PD1 & PD2 ]

Service SW

: stop of Vertical(Vramp) output ( For cutoff adjustment )

Analog Block

• Input stage => CVBS&Y/C input signals

Input level (CVBS) : 1.23Vp-p (173IRE) @max. / 1.0Vp-p @typ.

Input level (Y/C) : Y:1.00Vp-p (140IRE) @typ./ C:0.7Vp-p @typ.

• Output stage => RGB output signals

Output level

: 0.7 Vp-p (typ.)

Drive(R&G&B) : -3 to +4 dB by 7bit (White Balance)

Cutoff(R&G&B) : 0.5 V by 9bit (Start lighting point)

Digital Block

• 2DYCS

Adaptive YC separation by using of 1H line memory and original algorithm

• Luminance processing

Contrast

: 0 to 200 LSB by 7bit

Brightness

: -20 to 20 LSB by 8bit (Pedestal DC level)

Sharpness

: 0 to 3

dB by 5bit (by 0, 70, 140, 210ns)

Delay adjustment : 0 to 210 ns by 2bit(70ns step) to Chroma signal

Blackstretch

: 3 selectable stretch point

[ Stretch areas ( 0 to 25/30/40IRE ), Through areas ( 25/30/40IRE ~ ) ]

4 selectable blackstretch curves ( 1/4, 2/4, 3/4, 4/4)

• Chroma processing

Tint

: -45 to 45 degree by 7bit => about 0.7 degree

: Variable demodulator (R-Y) axis

(-22.5 to +22.5 degree by 6bit => about 0.7 degree)

Color

: 0 to 200

% by 7bit

• RGB matrix

ACL

EXT/RGB

BlueBack

Mute

Neck Protector

: Matrix(R-Y signal) ratio selectable (12/8, 13/8, 14/8)

: Automatic Contrast Limiter by MCU port(ADC) and I2C bus

: clip to 7LSB @ data < 0Fh

: ON/OFF selectable

: ON/OFF of R/G/B output

: R/G/B output to zero( no signal)

Deflection Block

• Horizontal Output

AFC2 phase

: +5 to -5µs by 5bit

Hold => Shut down : fh@Hold-down : in about 16.5KHz => fh@Shutdown : H-STOP

AFC1 gain

: Normal/High selectable for VTR skew

• Vertical Output

V position

: 0 to 16 H by 3 bit => 2H unit(connected with BLK)

V size

: 1.4 to 2.6 V by 7bit

Linearity

: 0 to 30 % by 7bit
