ILA8842
I²C BUS CONTROLLED SINGLE CHIP TV-RECEIVER
FEATURES
The following features are available:
•
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
•
Automatic Volume Limiting
•
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
•
PAL/SECAM/NTSC decoder
•
Base-band delay line for PAL and SECAM or chroma comb 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 alignment-free horizontal oscillator
•
Vertical count-down circuit
•
Vertical driver optimised for DC-coupled vertical output stages
•
I2C-bus control of various functions
GENERAL DESCRIPTION
The ILA 8842 is I2C-bus controlled single chip TV processor which is intended to be applied in
