KKA8842
KKA8842 is I2C BUS CONTROLLED SINGLE CHIP TV-RECEIVER manufactured by Kodenshi AUK Group.
FEATURES
The following features are available:
- Multi-standard vision IF circuit with an alignment-free PLL demodulator without external ponents
- Alignment-free multi-standard FM sound demodulator (4.5 MHz to 6.5 MHz)
- Audio switch
- Automatic Volume Limiting
- Flexible source selection with CVBS switch and Y(CVBS)/C input so that a b filter can be applied
- Integrated chrominance trap circuit
- Integrated luminance delay line
- Asymmetrical peaking in the luminance channel with a (defeatable) noise coring function
- PAL/SECAM/NTSC decoder
- Base-band delay line for PAL and SECAM or chroma b filter for NTSC
- Black stretching of non-standard CVBS or luminance signals
- Integrated chroma band-pass filter with switchable centre frequency
- Dynamic skin tone control circuit
- Blue stretch circuit which offsets colours near white towards blue
- RGB control circuit with "Continuous Cathode Calibration" and white point adjustment
- Possibility to insert a "blue back" option when no video signal is available
- Horizontal synchronization with two control loops and alignmentfree horizontal oscillator
- Vertical count-down circuit
- Vertical driver optimised for DC-coupled vertical output stages
