Overview

The 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.

  • 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
