TDA8840-N2 - NXP

TDA8840-N2 I2C-bus controlled PAL/NTSC/SECAM TV processors

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. The IF PLL demodulator .

Features

The 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 filt.
