Furthermore, this IC also supports high image quality systems and responds to needs from a diverse range of end
products.
Two independent inputs for the luminance and chrominance signals and switching between the Y1/C1 and Y2/C2 inputs
Video muting on/off switch
Built-in filters (The filter f0 adjustment function can be used to select the filter characteristics.)
Chrominance system: Bandpass filter (symmetric and asymmetric types)
Luminance system: Color trap and delay line
<Luminance System Circuit>
Built-in high image quality variable-type luminance system filter (color trap and delay line)
Luminance filter mode selection (f0 adjustment)
Four modes are provided: 3.58 MHz trap, 4.2 MHz trap, 5.0 MHz wide, and 10.0 MHz high band.
Peaking (sharpness) control
Aperture type control implemented using the delay line
The emphasis frequency is automatically selected according to the f0 mode using the delay line.
One of the four frequencies 2.2, 2.6, 3.0, or 4.9 MHz is emphasized according to which of the f0 modes (3.58 MHz
trap, 4.2 MHz trap, 5.0 MHz wide, or 10.0 MHz high band) is used.
Adaptive coring
For low-level signals, the above peaking is suppressed to reduce the image contamination due to that peaking.
The coring level is automatically adjusted according to the amplitude of the input signal.
Black stretch circuit: Can be turned on or off under control of the serial bus interface.
SYO (Selected luminance (Y) output)
One of the Y1/Y2 inputs is selected, and that input signal is output as the sync separator circuit signal directly.
However, the DC level of that signal is clamped at 1/2 VCC.
Also, this signal can be used for closed captions or as a velocity modulation.
Support for analog/digital OSD
Amplitude level limiting is applied to digital input signals internally to the IC.
Contrast and brightness controls
ABL (automatic beam limiter)
Three-pin system (IB IN, BRT ABL FILT, and CONTRAST ABL FILT pins), mode switching under control of serial
bus data.
R, G, and B output drive and bias adjustments
Sub-bias (brightness) control
The DC level of each of the R, G, and B signals can be adjusted over a 4-step (2-bit) range.
<Chrominance Circuit>
Built-in chrominance bandpass filter
Chrominance system filter mode selection: bandpass filter peaking/symmetric type selection and chrominance
bandpass filter bypass on/off setting
Auto Flesh: Flesh tone correction (on/off)
Overload (on/off)
Limits the saturation of the color when the ratio of the burst and color signals is large, i.e. when the color is highly
saturated.
Color phase and saturation controls
Demodulation angle: 104°
No. 5841-3/39
