I2C-bus controlled PAL/NTSC/SECAM TV processors

• Multi-standard vision IF circuit with an alignment-free
PLL demodulator without external components
• Alignment-free multi-standard FM sound demodulator
(4.5 MHz to 6.5 MHz)
• Audio switch
• Flexible source selection with CVBS switch and
Y(CVBS)/C input so that a comb filter can be applied
• Integrated chrominance trap circuit
• Integrated luminance delay line
• Asymmetrical peaking in the luminance channel with a
(defeatable) noise coring function
• 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
alignment-free horizontal oscillator
• Vertical count-down circuit
• Vertical driver optimised for DC-coupled vertical output
stages
• I2C-bus control of various functions
