TDA8841 datasheet


The various versions of the TDA8841 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 The IF PLL demodulator has been replaced by an alignment-free IF PLL demodulator with internal VCO (no tuned circuit required).


1. Multi-standard vision IF circuit with an alignment-free PLL demodulator without external components

2. Alignment-free multi-standard FM sound demodulator (4.5 MHz to 6.5 MHz)

3. Audio switch

4. Flexible source selection with CVBS switch and Y(CVBS)/C input so that a comb filter can be applied

5. Integrated chrominance trap circuit

6. Integrated luminance delay line

7. Asymmetrical peaking in the luminance channel with a (defeatable) noise coring function

8. Black stretching of non-standard CVBS or luminance signals

9. Integrated chroma band-pass filter with switchable centre frequency
