6-1-4. Function Description
1. Audio
Alignment free multi standard PLL audio demodulator (4.5 to 6.5 MHz)
Volume control
2. Video
Integrated fixed luminance delay line
Integrated chroma trap (auto calibrated)
Integrated chroma bandpass filters with switchable center frequency (auto calibrated)
Asymmetrical peaking circuit in the luminance channel with switchable noise coring
function
Black stretching of non standard CVBS or luminance signals, switchable via IIC-bus
3. RGB
RGB control (brightness, contrast, saturation)
Improved black current stabilization (continuos cathode calibration)
White point adjustment
Blue stretch which offsets colors near white to blue
Option to insert "blue back" when no video signal is available
4. Input/Output
Flexible video source select with CVBS input for the internal signal and two external video
inputs (one switchable for CVBS or Y/C)
The output signal of the video source select is externally available (also as CVBS when Y/C
Y/C input is used)
External audio input
Linear RGB input with fast blanking
5. Synchronization and Deflection
Horizontal synchronization with two control loops and alignment free horizontal oscillator
Slow start and slow stop of the horizontal drive output to enable low stress start-up and
Switch-off from the line circuit at nominal line supply voltage.
Vertical count-down circuit for stable behavior with provisions for non-standard signals
Vertical geometry control
Vertical drive optimized for DC coupled vertical output stages
