GENERAL DESCRIPTIONThe various versions of the TDA 884X/5X series are I2C-bus controlled single chip TV processors which are intended to be applied in PAL, NTSC, PAL/NTSC and multi-standard television receivers. The N2 version is pin and application compatible with the N1 version, however, a new feature has been added which makes the N2 more attractive. The IF PLL demodulator has been replaced by an alignment-free IF PLL demodulator with internal VCO (no tuned circuit required). The setting of the various frequencies (33.4, 33.9, 38, 38.9, 45,75 and 58.75 MHz) can be made via the I2C-bus.Because of this difference the N2 version is compatible with the N1, however, N1 devices cannot be used in an optimised N2 application.FEATURESThe following features are available in all IC’s:• 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
Key Features

FAQs
What is TDA8843?
The TDA8843 is a fully integrated 1-GHz Tuner and IF signal processor for TV and VCR applications. It is designed to meet the requirements of M/N, B/G, D/K, I, and PAL and SECAM standards.
How Does TDA8843 Work?
The TDA8843 works by receiving RF signals from the antenna and processing them into baseband video and audio signals suitable for TV and VCR applications. It integrates a tuner, IF signal processing, video and sound demodulators, and channel control into a single chip for simplified system design.
How Many Pins does TDA8843 have and What are the Functions of the Pinout Configuration?
The TDA8843 is housed in a multi-pin package. The pinout configuration includes:
- RF Input: Pin for connecting the radio frequency input signal.
- IF Output: Intermediate frequency output pin.
- Video Output: Pin for the video signal output.
- Audio Output: Pin for the audio signal output.
- Control Pins: Pins for controlling channel selection, mode settings, and other functions.
- Power Supply Pins: Pins for connecting to the power supply.
What are the Pros and Cons of TDA8843?
Pros:
- Integration: Fully integrated tuner and signal processor for simplified system design.
- Wide Compatibility: Meets the requirements of various TV standards.
